  1. let the total be x
    (x = men+women+children)

    1/4 of x are men, so (3/4)x is made up women and children
    but (2/5)((3/4)x = 132
    (3/10)x = 132
    3x = 1320
    x = 440

    so the total was 440, of which 110 were men, and 132 were women,
    leaving 198 children

    check my arithmetic and my thinking.

  3. Ignore 1/4 spectators, question is asking for remaining spectators.
    Remaining spectators = Women (W) + children (C)
    > Women = 2/5 of remaining spectators
    > Children = 1 - (2/5) = 3/5
    > 2/5 ------------>132
    3/5 ------------>C
    > Cross multiply:
    2/5 x C = 3/5 x 132
    C = (3/5 x 132)(5/2) :2/5 becomes 5/2 the other side to cancel out
    = (15/10)132
    = (3/2)132
    = 3(66)
    =198 Children
