Write each pair of fractions as a pair of fractions with a common denominator

3/4 and 7/8

2/3 and 1/4

7/10 and 4/5

The answer is:

6/8 and 7/8

8/12 and 3/12

7/10 and 8/10

To convert fractions into equivalent fractions, you have to first find the LCD or least common denominator of the fractions. For example, in the first, the LCD is 8.

Then divide the LCD by the current denominator. So 8 divided by 4 equals 2.

Next, multiply this number with the numerator. So 3 times 2 equals 6. And that's your answer.
