Explanation: Hello Students, time to learn examples. Let us take turns and read each example. Explain each step. Pay special attention to steps and pictures and communicate in your own words. |
Examples:
Reduce the ratio to the simplest form \$45 : 63\$.
Step 1a
|
|
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 1b
|
|
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 1c
|
|
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 1d
|
|
The ratio of reduction after division is 5:9. |
