Exercise 29 Page 246

To compare fractions with different denominators, we should first find a common denominator.

Practice makes perfect

In this exercise, we are given two fractions with different denominators. 2/4 ◯ 5/8To compare fractions with different denominators, we should first find a common denominator. Since 4 is a factor of 8 and 4 * 2 = 8, multiplying the numerator and denominator of 24 by 2 will give us a common denominator.

2/4

ExpandFrac

a/b=a * 2/b * 2

2 * 2/4 * 2

Multiply

4/8

Finally, we can make our comparison. Since 4 is less than 5, we know that the first value is less than the second value. 4/8 < 5/8 ⇔ 2/4 < 5/8
