How do you change 1.25 to improper fraction?
Well, 1.25 is basicly 1 1/4, right? So you multiply the denominator and the whole number together (4x1) and add the numerator (4x1+1). The answer is 5/4.
Why do you flip fractions when dividing fractions?
Flipped fractions are called reciprocals.We flip when we reposition a fraction from below the primary dividing line to above the primary, or vice versa, to simplify a calculation.Short answer: to simplify an expression that includes a fraction in its denominator or in its numerator.A flipped fraction is a shortcut version of a two step process of moving a fraction from a denominator to a numerator, or vice versa, to help us calculate the answer.To illustrate the long form of calculation :you can see that10 / 1/5 = 10 / 0.2 = 100 / 2 = 50Restating this example question to help you understand what is going on :10 x [ 1/ 1/5 ]which is merely separating the fraction in the denominator from the rest of the question by multiplying the fractional denominator [ alone ] by 1 or,more accurately, the whole expression given by 1/1. This has not changed the value of the final answer in any way.Let's make this very clear by considering ONLY the fractional denominator for a moment.1 / 1/5 times 1 / 1or1 x 1 / 1 x 1/5Now we can simplify this ugly-looking expression by relocating the lower level of denominator, the 5 , up to the primary numerator level, giving :[ ignoring the dots ]1 . 5_ x _ . which is simplified to : 5 / 1 or 51 . 1Now you already know that the final answer to the original question is 50or 10 x 5What we did there was MOVE the fraction in the denominator UP to the numerator without changing the overall value of the expression.We did that by reversing the fraction's numerator and denominator [ flipping both values ] when we repositioned the fraction up to the main numerator position.By it not changing the final answer when we did this, we have proven that the reciprocal of a fraction can replace [ or substitute for ] the fraction when the fraction is relocated above or below the primary dividing line, without affecting the final answer.Sounds confusing, doesn't it ?Just remember thatA over B/C is always equal to A x C/BC/B is called the reciprocal of B/Cand, of course, B/C can be termed the reciprocal of the fraction C/B.Dividing by a fraction is the same, mathematically, as multiplying by its reciprocal [flipping the fraction].There are perhaps two questions here:Why does it work?Why do we do it?I'll try to answer both questions:What you are really doing is multiplying the numerator and denominator by the same number (the flipped denominator). Multiplying this way does not change the value of the original problem by one of the rules of arithmetic (which we can prove). When you choose this flipped fraction to multiple by, you will see that it does something interesting to the denominator, mainly, it turns it into the value of one after you multiply and simplify. Since any number divided by 1 is itself, this simplifies the original fraction and turns the problem into the flipped fraction form.We do all this because the rule for multiplying fractions together is very simple: multiply the numerators together to get the numerator of the answer and multiply the denominators together to get the denominator of the answer.
What is the number below the fraction bar called?
The number below the fraction bar in a fraction is called the denominator. The denominator represents the total number of equal parts into which the whole is divided. It is crucial in determining the size of each part of the fraction and plays a significant role in mathematical operations involving fractions.
What is the denominator and the numerator together called?
A fraction
How would you times a fraction by a fraction?
-- Times the two numerators together to get the numerator of the answer. -- Times the two denominators together to get the denominator of the answer.
Why should there never be a negative sign in both the numerator and denominator of a fraction?
A fraction is really the numerator divided by the denominator. When you divide two negatives together you get a positive, so, you automatically change it to positive.
Is a numerator the opposite of the denominator?
Geographically if not mathematically. The numerator is the top number of a fraction and the denominator is the bottom number. They work together to tell how many parts out of the total number of parts are available.
How do you subtract two fractions with unlike denominators?
Make them into equivalent fractions with the same denominator, then the numerators can be subtracted and the resultant fraction simplified (if possible).The first choice is the denominator for the equivalent fractions. Ideally this should be the lowest common multiple (LCM) of the given denominators, but just multiplying the two given denominators together will do.The fractions can then be made into equivalent fractions with this chosen denominator.If finding the LCM is too difficult, a simple "butterfly" (or "cross multiply") method can be used:multiply the numerator of the first fraction by the denominator of the second fraction as the numerator of the equivalent first fraction;multiply the denominator of the first fraction by the numerator of the second fraction as the numerator of the equivalent second fraction;multiply the denominators together as the denominator of both of the equivalent fractions;subtract the new numerators, keeping the new denominator;simplify the result if possible.eg 3/5 - 1/2 = 3x2/5x2 - 5x1/5x2= 6/10 - 5/10= 1/10eg 5/6 - 1/2 = 5x2/6x2 - 6x1/6x2= 10/12 - 6/12= 4/12= 1x4/3x4= 1/3The same method is used for addition of fractions with different denominators: add instead of subtract the numerators of the equivalent fractions.
How do you times mixed fractions?
My strategy for multiplying mixed fractions: what you need to do is turn the mixed number into an improper fraction before you do any thing else. to do that you need to multiply the denominator with the whole number then add the numerator. now that number will be your numerator the denominator stays the same then you do the same to the other mixed fraction turn it into an improper fraction then once both are like that you multiply the numerators together to find the numerator then you multiply the denominators together to get the denominator then simplify your answer to get the right answer.
Can 11 and 1 eighth be written as a proper fraction?
A fraction is made up of two parts: a numerator (top number) and a denominator (bottom number). There are 3 types of fractions: Proper, Improper, Mixed. A proper fraction is one where the numerator is smaller than the denominator. An improper fraction is one where the numerator is larger or equal to the denominator. A mixed fraction is one with a whole number and a proper fraction together. 11 1/8 is a mixed fraction, and can be written as the improper fraction 89/8. It is impossible to write it as a proper fraction because the numerator is larger than the denominator. Also, all mixed fractions are improper fractions and no improper fractions can be written as proper fractions.
When do you add fractions when baking?
In order to add fractions, they must have the same denominators. If the fractions you wish to add do not already have the same denominators, they can be made to do so by finding the right number by which to multiply both the numerator and the denominator of each fraction. To find this number, multiply all the distinct denominators together, then multiply both the numerator and denominator of each fraction by a number found by the dividing the product of the distinct denominators by the denominator of the particular fraction concerned. All the fractions will then have the same denominator. Add the numerators of such fractions together to find the numerator of the sum; its denominator will be the one common to all the fractions.
Why do you have to multiply or divide the numerator or denominator of the fraction to find an equivalent fraction?
Equivalent fraction have the same value. Any whole number divided by itself is one Multiplying any number by 1 results in the same number. Thus when you multiply the numerator and denominator of a fraction by the same number, it leaves the value of the fraction the same, but the numerator and denominator will be different, creating an equivalent fraction. For example if you have a pizza and cut it in half, and take one of those pieces you will have 1/2 of the pizza. However, if you now cut the half you have and the half left on the plate into half again (each piece will be exactly the same size, a quarter of the pizza), you will still have half the pizza, but it will be made up of 2 of the 4 pieces of the pizza - you will have 2/4 of the pizza; thus 1/2 and 2/4 are equivalent fractions. Now, looking at those fractions again, what happens if you multiply the 1/2 by 2/2 (which is the same as multiplying by 2 ÷ 2 = 1): 1/2 x 2/2 = (1x2)/(2x2) = 2/4 so 1/2 and 2/4 are equivalent fractions. When dividing the numerator and denominator by the same number, this is really the same, but just going from a fraction with large numerator and denominator to one with smaller numerator and denominator - the reverse of the example above (sticking the pieces of pizza together again).
How do you add a fraction?
To add two (or more) fractions together:Find a common denominator (bottom number) by multiplying both the numerator (top number) and the denominator as necessary.Add the numerators together, over the same denominator.Simplify the fraction, if need be, or for ease.
Why is 1 over 3 equal to 2 over 6?
1/3 is equal to 2/6 as they are equivalent fractions. Equivalent fractions are made by multiplying (or dividing) both the numerator and denominator by the same value: 1/3 = (1×2)/(3×2) = 2/6 --------------------------------------------------------------------- This is a result of the way fractions are multiplied together (multiply the numerators together and multiply the denominators together), and a fraction with the same numerator and denominator is the same as the number 1 (since a fraction is equivalent to the the numerator divided by the denominator when converted to a decimal) and multiplying a number by 1 is the same as leaving the number alone: 2/2 = 2 ÷ 2 = 1 1/3 = 1/3 × 1 = 1/3 × 2/2 = (1×2)/(3×2) = 2/6
How do you add 3 fractions?
First, find the comman demoniater for all three. Then add the three numerators together and place the total over the common denominator. Next, reduce this new fraction if possible. Lastly, if the numerator is larger than the denominator, make a mixed number of it by dividing the denominator into the larger numerator.
