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 to subtract a fraction from a whole number?

Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly


When you add or subtract two like fractions when does the final answer have a different denominator?

Never. You could write a fraction as a mixed fraction if you like and then the mixed fraction would have a different denominator (e.g.: 23/2 = 11 1/2)


How do you add and subtract similar fraction?

Just simply add/subtract the numerators then copy the denominator.


How is subtracting fraction when numerator and denominator is the same?

If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!


When you subtract fractions do you subtract the denominator?

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.


How do you subtract fractions without mixed numbers?

First, turn the fraction into a improper fraction. Then find a common denominator between the two numbers. After this, subtract strait across, but leave the denominator the same.


How do you subtract a fraction?

Find a common denominator (make sure you multiply BOTH the numerator and the denominator) then subtract the numerators and simplify if necessary.


Can you subtract a fraction with the same denomintor and get a different denominator?

Only after simplification. If you subtract numbers with the same denominator, you have to put the original denominator in the result, but you can later simplify this, in some cases. A simple example: 3/4 - 1/4 = 2/4. Same denominator, but this can be simplified to 1/2.


How do you subtract mixed fractions when they have the same denominator?

The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.


What is a fraction with a denominator that has a different value?

It is a different fraction!


Why do fractions need a common denominator when adding subtracting?

In order to add or subtract one fraction from another, they must have a common denominator, or the same denominator. That's because it's impossible to add two fractions that have a different number of parts.
