Question

The average annual rainfall in Tucson, Arizona is 12 inches. Between January and April 2.4 inches of rain fell. What percentage of the annual rainfall fell after April (May through December)? You may want to draw a diagram to organize information.​

Answer 1

Answer: 80%

Step-by-step explanation:

Annual rainfall in Arizona = 12 inches
Rainfall between January and April = 2.4 inches.
Rainfall after April = Total Rainfall.

Total rainfall - Rainfall till April = 12 - 2.4 = 9.6 inches.

% of Rainfall after April = $\frac{Rainfall after April}{Total Rainfall} x100$ =  $\frac{9.6}{12} x 100$ = 80%
