Exercise 28 Page 290

How can you compare two fractions with different denominator?

7/8 > 3/4

Practice makes perfect

In this exercise, we are given two fractions with different denominators. 7/8 ? 3/4To compare fractions with different denominators, we should first find a common denominator. Since 4 is a factor of 8, multiplying the numerator and denominator of 3 4 by 2 will give us a common denominator.

3/4

a/b=a * 2/b * 2

3*2/4*2

Multiply

6/8

Finally, we can make our comparison. Since 7 is more than 7, we know that the first value is more than the second value. 7/8 > 6/8 ⇔ 7/8 > 3/4
