Last sunday, 1,575 people visited the amusement park. 56% of the visitors were adults, 16% were teenagers, and the rest were children ages 12 and under. how many children under 12 visited the park?

First we less the sum of 56% and 16% from 100% to get our percentage of visitors under 12.

Percentage of visitors under twelve = 28%

Then we take 28% of 1,575.
Easiest done if we use the fraction .28 instead of 28%.

Number of visitors under twelve= 441
