First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.

What the fraction of 0.7 but same denominator as 4?

4 is an integer and so has denominator 1. 0.7 is a proper fraction and cannot have a denominator of 1.


What part of the fraction does not change when you add or subtract?

If you find the common denominator for the fractions, then the bottom will stay the same :) BUT sometimes it is diffacult to find the common denominator so you may need help


How do you answer fraction problems?

The best way to answer fraction problems is with a fraction that has the same denominator or a common denominator with those in the original problem. Typically you also need to reduce it so that the final answer does not contain an improper fraction.


How do you change 0.8 into a fraction?

since the last number (8) is in the tens place you have 10 as the denominator (same for thousandths = 1000 as denominator, hundredths = 100 as denominator and so on) then put the decimal number as the numerator and you get the answer of 8/10


How do you change a percent into a fraction?

One way to change a percent into a fraction is to take the percent number and but the denominator as 100. For example if the percent number was 43 then that would be your numerator and 100 would be your denominator so it should be 43/100. Percent means out of 100 so your denominator should be 100 unless you simplify your fraction.


What is the reciprocal for seven over three?

The reciprocal of a fraction is basically the same fraction flip-flopped. So the numerator becomes the denominator, and the denominator becomes the denominator. So for seven over three, the reciprocal would be three over seven.


When two fractions refer to the same whole explain why the fraction with a lesser denominator has larger pieces than the fraction with a greater denominator?

The fraction with the smaller denominator has fewer pieces in the whole. So each piece must be bigger.


How do you change an mixed fraction to an improper fraction?

ex.1 2/3 take the base number and multiple that by the denominator and add by the numerator andAwhatever you get for that is your new numerator but you denominator stays the same as the last one so for this example you should get 5/3.


What is the reciprocal of seven over thirty one?

The reciprocal of a fraction is the same fraction flip-flopped. So the numerator becomes the denominator, and the denominator becomes the denominator. So for seven over thirty one, the reciprocal is thirty one over seven


How do you simplify a fraction numerator and denominator the same number?

If the numerator and denominator are the same then their GCF is also the same number. So the fraction can be written, it is simplest form as the integer, 1.


How do you simplify a fraction when the numerator and denominator is the same number?

If the numerator and denominator are the same then their GCF is also the same number. So the fraction can be written, it is simplest form as the integer, 1.


How do you change a proper fraction into a inproper?

Multiply it by a number that is large enough so that the numerator of the fraction becomes larger than its denominator.


What is the rule for subtracting fractions?

First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).


Is there such thing as a fraction with 100 as the denominator?

Any real number can be the denominator in a fraction. A fraction is a way of expressing one number (the numerator, the "top" number in a fraction) by another (the denominator, "bottom number.") So it is possible to have a denominator of 100.


How do you change 65 percent to a fraction?

When you change a percentage to a fraction the denominator (bottom number) of the fraction will always be 100. The percentage will be the numerator (top number), so 65% as a fraction is 65/100. This can then be simplified by dividing both the numerator and denominator by their greatest common factor, which is 5. The final answer is 13/20.


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.


How to change dissimilar fractions to similar fractions?

Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.


How do you make fraction a decimal?

To make a fraction a decimal, you divide the numerator by the denominator. The numerator is on top and the denominator is on the bottom. so 3/4 would be the same as 3 divided by 4 which is 0.75.


What is a fraction with a numerator that is greater than or equal to the denominator is an?

if the numerator is bigger then the denominator it is called an improper fraction so you have to divide to get your regular fraction.


Why is a numerator less than the denominator?

a numerator can be more than the denominator but, if it is it is a improper fraction. so the numerator is less than the denominator do the fraction can be proper.


How do you subtract a fraction with a different denominator?

change the denominators to be the same, as you would for addition, so if you have 1/2 minus 1/4 - change the 1/2 to be 2/4 (denominators are the same) to do this multiply denominator by a number that equals the other denominator, in this case 2 and then times it to the top number, hence 2/4. Now you have 2/4 - 1/4, 2-1=1 so the answer is 1/4


How do you rename each mixed number in simplest form?

you can rename a mixed number in the simplest form by taking the number and multiplying the number by the denominator and add the numerator to that number and keep the same denominator and use the number that you got by multiplying and adding as the numerator and keep the denominator the same then you will end up with an improper fraction and how to change the improper fraction into a mixed number is to divide the numerator from the denominator and you will end up with a remainder and so your answer on top becomes the number and the remainder becomes the numerator and the number out of the dog house is your denominator


How do you make fractions into decimals and rounded off to 2 decimals places?

Example: If the fraction is 3/10, then the decimal is: 0.3 How? The denominator of the fraction is 10. So, there is only one zero right? Ans: 0.3 Example 2: If the fraction is 3/5, you have to change the denominator to, 10,100 or thousands or else you can't change it to a decimal. So, the denominator 5 is closest to 10. To change the 5 to 10, you have to 5 times 2 = 10 If you times the denominator, you have to times the numerator too. so the fraction becomes: 6/10. 6/10 is 0.6 If you want to round off to 2 decimal places, then....


How do you change proper fraction into equivalent fraction?

A proper fraction is when the numerator is smaller than the denominator: 1/2,3/4, and so on. An equivalent fraction is when different fractions have the same value: 1/2 = 2/4 = 5/10 all mean a half of something.


What values in the denominator must you be mindful of?

The denominator cannot be 0. If the denominator is a negative number, a fraction, a surd or a complex number (depends on your level), you are expected to rescale the fraction so that the denominator is a positive integer.
