Question

Mark (✓) against the correct answer
A worker makes a toy every $\frac{2}{3}$ hour. If he works for $7\frac{1}{3}$ hours, then how many toys will he make?

(a) 22
(b) 18
(c) 16
(d) 11

Answer 1

No. of toys made in $\frac{2}{3}$ h = 1
No. of toys made in 1 h = $\frac{3}{2}$
No. of toys made in $7\frac{1}{3}$ h = $\frac{3}{2}\times \frac{22}{3}=11$

Hence, the worker will make 11 toys in $7\frac{1}{3}$ h.

The correct option is (d).
