Question

How much fraction of the total sales of aquarium was done by a store in the third quarter of the year 2021?

• A. $\frac{1}{4}$
• B. $\frac{1}{3}$
• C. $\frac{1}{2}$
• D. $\frac{2}{3}$

Answer 1

The correct option is B $\frac{1}{3}$

Let's count the number of aquariums sold in each quarter of the year 2021.

Total sales = 60 + 100 + 120 + 80 = 360
Now, fraction of the total sales done in July - September = $\frac{120}{360}$ = $\frac{1}{3}$
