    72 runners

    Step-by-step 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
