Answer:

24 boys and 32 girls

Step-by-step explanation:

Since there are 3 boys for every 4 girls, we assume that there are 7 children in each set of children.

in order to get the number sets of children inside the bus we divide the total number of children which is 56 into the number of children in each set which is 7.

56 ÷ 7 = 8; therefore, there are 8 sets of children inside the bus.

To solve the number of girls and boy inside the bus we simply multiply number of girls and boys in first set to the number of sets of children.

3 ( number of boys in first set of children) x 8 ( total number of sets) = 24; therefore, there are 24 boys in total inside the bus

4 ( number of girls in first set of children) x 8 ( total number of sets) = 32; therefore, there are 32 girls in total inside the bus
