No of Girls

X x 4/7=18

(X x 4/7)/(4/7)=18(4/7)

X=18(4/7)

X=(18x7)/4 reciprocal

X=56/4

X=14

Total No of Children

18boys+14girls

18+14=32 Children

4/7= Boys, 3/7= Girls there are 1/7 more boys than girls. There are 18 more boys than girls.

1/7=18/X

(18)1/(18)7=18/X

18/126=18/X

X=126

72 boys + 54 girls = 126 total kids
