Answer

Problem

Reduce the given fraction \$65/99\$to its simplest form.

Hint

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

Step

Factors for 65 is
Factors for 99 is

1, 3, 5, 13, 25, 65
1, 3, 9, 11, 33, 99

Step

The GCD for 65 and 99 is

Step

Divide both the numerator and the denominator by the GCD

\$(65 ÷ 3)/(99 ÷ 3)\$ = \$25/33\$

Step

So, after simplifying, we get \$25/33\$.

Answer

Option
