### Instruction:
The ratio of boys to girls in a family is 5:7. The total number of children in the family is 180. If the boys are given $3900 to share, how much money does each boy receive?

### Response:

The total number of children in the family is 180.
The ratio of boys to girls is 5:7.
The ratio of boys to total number of children is 5:180.
The ratio of girls to total number of children is 7:180.
The total amount of money to share is $3900.
The ratio of boys' share to total amount of money is 5:3900.
The ratio of girls' share to total amount of money is 7:3900.
The number of boys is 5/5 = <<5/5=1>>1.
The number of girls is 7/5 = <<7/5=1.4>>1.4.
The total number of children is 1 + 1.4 = <<1+1.4=2.4>>2.4.
The boys' share is 5/3900 = <<5/3900=0.001282>>0.001282.
The girls' share is 7/3900 = <<7/3900=0.001791>>0.001791.
The total amount of money to share is 0.001282 + 0.00
