Answer

Problem

Find the equivalent fraction of \$72/90\$.

Hint

To find the greatest common divisor (GCD) for each number.

Step

Factors for 72 is Factors for 90 is

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Step

The GCD for 72 and 90 is

Step

Divide both the numerator and the denominator by the GCD

72 ÷ 18 = 4
90 ÷ 18 = 5

Step

So, the equivalent fraction of \$72/90\$ is

\$4/5\$
