Best Answer

If the fractions have the same denominator, just add or subtract the numerators.

13/20 - 9/20 = 4/20

2/5 + 1/5 = 3/5

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

similar-a similar radicand is to add or subtract similar radicals we simply add and subtract there coefficients and Anex to the sum of their common radical part.

You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.

just add , subtract , multiply , and , divide

Make it into an both numbers an improper fraction and then do the opperation.

i think you just add it and put the negative sign in front of it

A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...

If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
