Answer 1

`Girls = 319`

Explanation:

Given

`Boys: Girls = 15:11`

Required

Find Girls, when Boys = 435

Substitute 435 for Boys

`435: Girls = 15:11`

Express as fraction

`(Girls)/(435) = (11)/(15)`

Multiply through by 435

`435 * (Girls)/(435) = (11)/(15)* 435`

`Girls = (11)/(15)* 435`

`Girls = (11* 435)/(15)`

`Girls = (4785)/(15)`

`Girls = 319`
