Question

The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?

Answer 1

222 boys in the class hope this helped

Answer 2

`222` boys

Explanation:

Let
`x` = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

`(5)/(6+5)x = 185` (number of girls in ninth grade)

`(5)/(11)x = 185`

`x=407`

To find for the number of boys, we can use substitution:

`(6)/(6+5)x = (6)/(11)(407)`

`=222`

∴ There are
`222` boys in the class.

Hope this helps :)
