Question

2/5 of a class are girls. 3/4 of the boys are called Paul. What fraction of the whole class is not called Paul?

Answer 1

3/20

Explanation:

If 2/5 are girls then to find boys, calculate

1(the whole class) - 2/5 which is 3/5.

Then if 3/4 of the boys are called Paul, that means the remaining 1/4 aren't.

1/4 × 3/5 = 3/20

Answer 2

1/4

Explanation:

3/4 + 1/4 = 4/4
