Question

Parent-teacher interviews were held on

Thursday. Of those parents who
attended, 1/6 attended in the morning,
1/3 attended in the afternoon,
and the rest attended in the evening.
a) What fraction of the parents
attended in the evening?
b) Thirty parents attended the
interviews. How many parents
attended in the evening?

Answer 1

Explanation:

1/6 attended in the morning.

1/3 attended in the afternoon.

1/6 + 1/3

1/6 + 2/6 = 3/6

3/6, or 1/2 attended in the morning and afternoon combined.

a) If 1/2 attended in the morning and afternoon combined, then the other 1/2 attended in the evening.

b) 1/2 of 30 = 15, so 15 parents attended in the evening.
