How to Calculate Ratio. Example: The ratio of girl to boy in a class is 12:16. To simplify the ratio we can make the numbers into smaller ratios so as to compare easily. This can be done by dividing the ratio by same number on each side.Dividing 2 on both 12 and 16 as 2 is the common factor: $\frac{12}{2}$ = $6$.$\frac{16}{2}$ = $8$. So, 12: 16 is simplified into 6: 8.ow to Calculate Ratio. Example: The ratio of girl to boy in a class is 12:16.
