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.

You are watching: 8/15 in simplest form

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

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

Example 1: Multiply the fractions 10/15 and 1/5. First, 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.

Example 2: Multiply the fractions 2/3 and 2/3. First, 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. 2 x 2 and 3 x 3 The answer is 4/9, this is already in it"s simplest form. You don"t need to reduce this fraction.

## How do you divide fractions?
