    B) 14

    Step-by-step explanation:

    1/5 + 1/3 = x (don't worry, it's not algebra, I'm just using x as an example)

    The common denominator is 15, so you multiply 5 by 3 = 15 and 1 by 3 = 3,

    3/15 = 1/5

    Then, multiply 3 by 5 = 15 and then 1 by 5 = 5, so it's

    5/15 = 1/3

    5/15 + 3/15 = 8/15 and then multiply 15 by 2 = 30 (number of students) and because you multiplied 15 by 2, you also multiply 8 by 2 = 16

    So it is now 16/30, so you do 30-16 which is 14.

    14 students chose Station M (doesn't sound like a good station).

    Whoo! Let's go! (I'll stop being cringy now).

    14

    Step-by-step explanation:

    30/3 = 10

    30/5 = 6

    10 + 6 = 16

    30 - 16 = 14
