Answer 1

`(3)/(5)`

Explanation:

In the fifth grade class,
`(4)/(5)` of the girls have brown hair. Again among those of the brown-haired girls,
`(3)/(4)` of them have long hair.

We are asked to find the fraction of the girls who have long brown hair in the class.

The fraction of the total students which have long brown hair will be (
`(4)/(5) * (3)/(4)`) =
`(3)/(5)` . (Answer)
