Strawberries

In a class of 45 students, 1/3 of the students are girls. If 1/3 of the girls enjoyed eating strawberries and 1/5 of the boys enjoyed eating strawberries, how many students in a class enjoyed eating strawberries?

Correct answer:

s =  11

Step-by-step explanation:

$$\begin{gathered} n=45 \\ g=\frac{1}{3}\cdot n=\frac{1}{3}\cdot 45=\frac{1\cdot 45}{3}=\frac{45}{3}=15 \\ b=n-g=45-15=30 \\ s=g/3+b/5=15/3+30/5=11 \end{gathered}$$
