Question

In a class of 25 students, there are 20 boys and 15 girls. What is the ratio of boys to girls? (hint-- write this ratio as a fraction)

Answer 1

The ratio of boys to girls is

`(4)/(5):(3)/(5)`

Explanation:

In a class the total number of boys and girls are 25

Total of boys are 20 and total of girls are 15

Let x be the number of boys and y be the number of girls

Given x=20 and its ratio is

`x=(20)/(25)`

`x=(4)/(5)`

and y=15 and its ratio is

`y=(15)/(25)`

`y=(3)/(5)`

Therefore the ratio of boys to girls is

`x:y`

`(4)/(5):(3)/(5)` or

`4:3`
