Verified Answer :

To get the ratio we have to put into numerator number of girls and into denominator number of boys. Then simplify it
\(\frac{16}{20}= \frac{16:4}{20:4}= \frac{4}{5}\)
It also can be denoted as 4:5

the ratio of girls to boys is 4 to 5 in simplest terms. U need to divide both the 16 and 20 by 4, and u get 4 and 5. Since 4 represents girls, it comes first and the ratio is 4 to 5 or 4:5
