Reduce the ratio to the simplest form: \$45 : 63\$.

Step: 1

First, convert the ratio into a fraction form.
\$(45)/(63)\$

Explanation:

To start, we need to convert the given ratio into fraction form. The ratio we are given is \$(45)/(63).\$

Step: 2

We have determined that the greatest common divisor (GCD) of 45 and 63 is 9.

Explanation:

Here, we perform the greatest common divisor of 45, and 63 has been calculated is 9.

Step: 3

For this step, we need to divide both the numerator and denominator by 9.
\$(45 \div 9)/(63 \div 9)\$ = \$5/7\$

Explanation:

Let’s take a step forward by dividing both the top and bottom numbers by 9. This will help us reach our goal.

Step: 4

The ratio of reduction after division is 5:7.

Explanation:

The result of dividing has a reduction ratio of 5:7.
