If there are 4 boys and 2 girls in a family, what is the ratio of boys in the family to children in the family?

Boys = 4
Children = Boys + Girls = 4 + 2 = 6

This means that the ratio of boys to children is 4:6
You can also simplify this to 2:3  

In this case, this means that for every 3 children, 2 of them will be boys.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
