of the total number of spectators at a circus show, 1/4 are men, 2/5 of the remaining number of spectators are women. there are 132 women at the circus show. how many children are at the circus show?
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.
