let's the number of the children in the club be x
given: 2%2F5 of the children in the club are girls...->...
girls=%282%2F5%29x

%282%2F5%29x+%2B24=x
2x%2F5+%2B24=x
2x%2A5%2F5+%2B24%2A5=x%2A5
2x+%2B120=5x
120=5x-2x
120=3x
120%2F3=x
40=x.........there are altogether 40 children

girls=%282%2F5%29x=%282%2Fcross%285%29%29cross%2840%298=2%2A8=16..there are 16 girls
