How can you compare two fractions with different denominators?

>

Practice makes perfect

When comparing numbers, it is best to first ensure that they are as similar as possible. In this exercise, we are given two fractions with different denominators. 3/6 ? 1/8 To compare fractions with different denominators, we should first find a common denominator. Multiplying the numerator and denominator of 36 by 4 and the numerator and denominator of 18 by 3 will give us a common denominator.

3/6 ? 1/8
3*4/6*4 ? 1/8
12/24 ? 1/8
12/24 ? 1*3/8*3
12/24 ? 3/24

Now we can determine which symbol will make a true statement. 12/24 > 3/24 ⇔ 3/6 > 1/8
