Question

Bruce's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 12 espressos in all, 9 of which were single-shot. What percentage of the espressos were single-shot?

Answer 1

Answer: 75%

Explanation:

Since 9 out of the 12 that were sold were single shot, that means 9/12 of them were single-shot.

We can divide both the numerator and denominator by 3, and we get that 9/12 = 3/4.

3/4 as a percent is 75%.
