# Comparing Fractions Quickly

When given two fractions, there is a cool little trick to help figure out which fraction is the larger.

Let’s compare 3/8 and 4/9.

Multiply the numerator of the first fraction (the top number in the fraction) by the denominator (the bottom number in the fraction) of the second fraction. Then compare the two answers.

- 3 * 9 = 27
- 4 * 8 = 32

Since 32 is larger than 27 we know that 4/9 > 3/8. Make sure that the answers relate to the numerator. In this example 27 relates to 3/8 and 32 to 4/9.
