Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
First you add the fractions then add the whole numbers I'd you can you can reduce the fractions bye multiplying Hope you have fun!😺🐆💙💎💖🐾
Only if the denominators are different.
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
it stay the same when you subtract fractions and when you add fractions.
Find their least common denominator and convert them.
Yes.
if it has a denominator
Yes, you are.
no, to add and subtract like and unlike fractions the denominator has to be the same,
numerators you add, denominators you leave it the same
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.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
In order to add or subtract fractions, they must have the same denominator.
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
