Exercise 42 Page 124

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. 7/9 ? 5/11 To compare fractions with different denominators, we should first find a common denominator. Multiplying the numerator and denominator of 79 by 11 and the numerator and denominator of 511 by 9 will give us a common denominator.

Now we can determine which symbol will make a true statement. 77/99 > 45/99 ⇔ 7/9 > 5/11
