The number of girls and boys in a class are in the ratio 7: 5 and there are 8 more girls 10 boys. how many girls and boys are there in the class.

Answer 1

number of girls ---- 7x
number of boys ---- 5x

"there are 8 more girls 10 boys" makes no sense

are you saying, "there are 8 more girls than boys" ?

which translated into math would be
7x = 5x+8

take it from here
