Exercise 29 Page 290

In this exercise, we are given two fractions with different denominators. 1/3 ? 7/9To compare fractions with different denominators, we should first find a common denominator. Since 3 is a factor of 9, multiplying the numerator and denominator of 1 3 by 3 will give us a common denominator.

Finally, we can make our comparison. Since 3 is less than 7, we know that the first value is less than the second value. 3/9 < 7/9 ⇔ 1/3 < 7/9
