Question

In one school, 5/6 of the sixth-graders take a foreign language. Of these students, ⅖ take French.

a.What fraction of the sixth-graders take French?

b.If there are 150 sixth-grade students, how many take French?

Answer 1

5/6 x 150 = 125 take a foreign language

2/5 x 125 = 50 take French.
Or 5/6 * 2/5 = 10/30 = 1/3 and 1/3 x 150 = 50 take French.
