    C.) 21
    Jason will complete 21 laps in 35 minutes.

    To solve this, you would have to set up a proportion to find the missing term

    3 laps / 5 minutes = “x” laps / 35 minutes

    Multiply the numerator of the first fraction (3) by the denominator of the second fraction (35)

    3 * 35 = 105

    Divide 105 by the denominator of the first fraction (5)

    105 / 5 = 21
    So… x = 21 laps

    The answer is C because 35 divided by 5 is 7 and 7 times 3 is 21

    You have to see how many groups of 5 can go in 35 and then you multiply the amount of groups with the amount of laps Jason can jog in 5 minutes and you get 21
