How do you minnous fractions?

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

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.


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.


Do you add and subtract like and unlike fractions in the same way?

no, to add and subtract like and unlike fractions the denominator has to be the same,


How do you add and subtract improper fractions with different denominator?

he fact that they are improper is irrelevant. Re-scale the fractions so that they have the same denominator and thenadd or subtract as required.


How are fractions under addition?

In order to add or subtract fractions, they must have the same denominator.


Why do you need a common denominator with fractions?

You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.


How do you add or subtract dissimilar fractions?

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.


How do you find the difference of two fractions with the same denominator?

Subtract as if there were no denominators.


What are the steps to subtracting fractions?

Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.


How do you subtract fractions when denominator is different?

By finding the lowest common denominator of the fractions.


How do you subtract fractions when the first numerator is smaller than the other numerator?

if they have the same denominator just subtract it . if it doesn't than find the denominator.

How do you add or subtract fractions when negative?

The same as with positive ones. Make sure they have the same denominator and add or subtract their numerators.


How do you add and subtract by fractions?

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.


What do you do when you're going to subtract fractions but the numerator is the same?

Whether the numerators are the same or not, you need to get the denominators to be the same. First, find the least common denominator. Then convert the fractions to equal fractions that use the common denominator. Then you can subtract the fractions by subtracting the numerators. Finally, look for common factors between the numerator and the denominator of the difference in order to put the answer in simplest terms.


Why do you need a common denominator?

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.


When 2 or more fractions have same denominator?

If you are adding or subtracting fractions with the same denominator, you can add or subtract the numerators and keep the denominator the same. 1/8 + 3/8+ 3/8 = 7/8, for example


How do you subtract fractions with a common denominator?

If the two bottom numbers are the same, you will carry that same number over to the denominator in the answer. To get the numerator (top number) simply subtract the two numerator and place the number over the answer denominator.

It stays the same. Only the numerators change.


What is the meaning of addition and subtraction of similar fraction?

Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
