Question

Jing's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 20 espressos in all, 16 of which were single-shot. What percentage of the espressos were single-shot?

Answer 1

16/20 = p/100

 

Cross multiply.

 

20p = 1600

p = 80

 

Or, 16/20 = 0.8 = 80%
