Why do you have to multiply or divide both the numerater and denominator of a fraction to find an equivalent fraction?
Whatever you multiply or divide the numerator by, you must do the same to the denominator. If you multiply or divide the numerator and denominator by different numbers, you change the value of the fraction and turn it into a different number. After that, nothing is "equivalent" any more ... you're working with a changed number.
What happens when you divide a number by 0.5?
When you divide a number by 1/2, you multiply it by 2. Imagine that you are dividing two fractions ; 1/1 / 1/2. In order to divide the fractions, you must flip the second fraction making it 2/1 and then multiply 1/1 by 2/1. This will give you two. Thus 1/0.5=1*2.
How do you check an equivalent fraction with multiplication and division?
If you start with a fraction p/q and are told that x/y is an equivalent fraction, then the simplest check is to cross-multiply: p*y must be equal to q*x.
How do you divide 0.5 by1.41?
Make the divisor (1.41) a whole number and then divide normally. To make the divisor a whole number, the easiest way is to keep multiplying it by 10 until it becomes a whole number; but remember, division is just like a fraction - whatever you do to the denominator (bottom) you must also do to the numerator (top) - so whatever you do to the divisor (the number by which you are dividing) you must do to the dividend (the number into which you are dividing): 0.5 ÷ 1.41 = 50 ÷ 141 (multiply both by 100) = 50/141 ≈ 0.3546
What do you do when you are dividing a fraction?
When dividing a fraction you leave the first fraction as it is and you change the second fraction into a reciprocal (flip the fraction). Once you have changed the second fraction into a reciprocal, then you would simply *multiply the two fractions together. Once you multiply the two fractions then that would be your final answer. Dont forget to simplify! And remember if the fractions are mixed numbers before you do anything you must change the mixed numbers into improper fractions first! hope this helps! *If you dont know how to multiply fractions then thats a different question
One tenth of 80?
A fraction "of" a number is the same as the fraction "times" a number. In other words, you must multiply 1/10 times 80.A fraction "of" a number is the same as the fraction "times" a number.

How do you convert a fraction into a decimale?
To convert a decimal into a fraction you must multiply the numerator by the denominator.

Why do you use the reciprocal when dividing fractions?
Think of it like this.... If we are dividing fractions and we set those fractions up in a fraction such as, 2/3 ___ 3/4 then how would we get rid of the bottom fraction? We would multiply it by the reciprocal 4/3, so that it's now equal to one, and then because we multiplied the bottom by 4/3, we must also multiply the top by 4/3. So now we have... 2/3 * 4/3 _______ 3/4 * 4/3 = 8/9 ___ 1 = 8/9 That's why we multiply by the reciprocal of a fraction when dividing! E2020 people this should be in your notes? The reciprocal is one of two numbers whose product is 1; it is also called multiplicative inverse.
How do you multiply a fraction by a whole number?
To multiply a fraction by a whole number, you must treat the whole number as a fraction by using 1 as the denominator (bottom number of the fraction). Example: 3/4 x 5 would be written 3/4 x 5/1. Then multiply the two numerators (top numbers) together for the numerator of the product fraction, and multiply the two denominators together for the denominator of the product. Thus 3x5 = 15 and 4x1 = 4 which would be the product 15/4. The next step is to convert the fraction to a mixed number by dividing the numerator by the denominator (15/4 = 3 r 3) which would be the final answer of 3-3/4.
What do you do when scaling up fraction?
when you scale a fraction up you have to multiply by a number that will get the denominator to the same number. But what you do to the bottom you must do to the top.
How can you change a fraction to make it denominator 100?
To make a fraction have the denominator 100, you need to multiply and divide until this is the case. The one thing to remember is that anything that is done to the denominator must also be done to the numerator. For example, if we take the fraction 7/14, we could start by dividing top and bottom by 7 to give us 1/2. The next step would be to multiply top and bottom by 50 to give us 50/100. Thus 7/14 = 50/100 as a fraction with denominator 100.
How do you write 0.00006 as a fraction?
3/50000(simplified) or 6/100000, an easy way to figure out decimals like this is dividing by 10 moves the decimal point back by 1. So starting at 6, the decimal must move 5 places, so dividing 6 by 100000 (6/100000) will make 0.00006. If you must move the decimal forward do the opposite and multiply.

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.
