Multiplying Fractions

Fractions can be multiplied.

Imagine you wanted to multiply 2/5 (two-fifths) with 1/3 (one-third).

How to Multiply Fractions


Multiply the fractions below.



Multiply the top numbers (called the numerators) of the fractions together.

2 × 1 = 2


Multiply the bottom numbers (called the denominators) of the fractions together.

5 × 3 = 15


The answer from Step 1 is the numerator of our answer. The answer from Step 2 is the denominator of our answer.


Simplify the fraction if possible. (The fraction in our example is already as simple as possible).


2/5 (two-fifths) multiplied by 1/3 (one-third) equals 2/15 (two-fifteenths).

2/5 × 1/3 = 2/15
