Example: For adding the fractions 1/3 and 1/5, you must first modify the fractions so that the denominators are the same. For these two fractions, the result would be 5/15 and 3/15.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
5 + 3 = 8.

The sum is 8/15

How do you subract fractions?

Example: For subtracting the fractions 10/15 and 1/5, you must first modify the fractions so that the denominators are the same. For these two fractions, the result would be 10/15 and 3/15.
The second step is to subtract the numerators of the two fractions to find the numerator of the answer,
10 - 3 = 7.
The difference is 7/15

How do you multiply fractions?

Example: For multiplying the fractions 10/15 and 1/5, you multiply the numerator of the first fraction by the numerator of the second fraction to find the numerator of the answer. You also multiply the denominator of the first fraction by the denominator of the second fraction to find the denominator of the answer. 10 x 1 and 15 x 5
The answer is 10/75, then reduced to the simplest form is 2/15.

How do you divide fractions?

Example: For dividing the fractions 10/15 and 1/5, you first find the reciprocal of the second fraction. The reciprocal of 1/5 is 5/1 . You then multiply the first fraction by the reciprocal of the second fraction.

10/15 ÷ 1/5
is the same as
10/15 x 5/1

The answer is 50/15 , reduced the simplest form is 10/3 .
