Question

There are 420 students. 63 students were out sick. What percent of the student population is ill?

Answer 1

15% of the student population is ill.

Answer 2

To find the percentage,here's what we can do:
$\frac{student \: out \: sick}{original \: population} \times 100\%$

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%

Therefore the answer is 15%.

Hope it helps!
