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. 10/17 ? 11/12 To compare fractions with different denominators, we should first find a common denominator. Multiplying the numerator and denominator of 1017 by 12 and the numerator and denominator of 1112 by 17 will give us a common denominator.

10/17 ? 11/12
10*12/17*12 ? 11/12
120/204 ? 11/12
120/204 ? 11*17/12*17
120/204 ? 187/204

Now we can determine which symbol will make a true statement. 120/204 < 187/204 ⇔ 10/17 < 11/12
