Answer: There are
children at the circus show.
Step-by-step explanation:
Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.
Knowing that
of the spectators are men, we can find the remaining:
![x-\frac{1}{4}x=\frac{3}{4}x](https://tex.z-dn.net/?f=x-%5Cfrac%7B1%7D%7B4%7Dx%3D%5Cfrac%7B3%7D%7B4%7Dx)
Since
of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:
![(\frac{2}{5})(\frac{3}{4}x)=132](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B5%7D%29%28%5Cfrac%7B3%7D%7B4%7Dx%29%3D132)
Solving for "x", we get:
![x=(132)(\frac{20}{6})\\\\x=440](https://tex.z-dn.net/?f=x%3D%28132%29%28%5Cfrac%7B20%7D%7B6%7D%29%5C%5C%5C%5Cx%3D440)
Therefore, we get that "c" is:
![c=440-\frac{1}{4}(440)-132\\\\c=198](https://tex.z-dn.net/?f=c%3D440-%5Cfrac%7B1%7D%7B4%7D%28440%29-132%5C%5C%5C%5Cc%3D198)
