Answer 1

72 runners

Explanation:

Total runners = 360

20% of the total runners are in the 35-39 age bracket.

We need to find number of runner in this age bracket.

Which tells us that this number is simply 20% of the total, or 20% of 360.

How to find percentage of number?

We convert percentage to decimal and then multiply it with the other number.

Converting percentage to decimal requires us to divide by 100. So:

20% = 20/100 = 0.2

Now,

0.2 * 360 = 72

Hence,

72 runners are in the 35-39 age bracket
