You can put this solution on YOUR website! Since you know that for every 3 boys there are 5 girls, you can multiply the numbers by a common number and the ratio will stay the same. I will multiply by 2:
In the ratio 6:10 there are 4 more girls than boys, let me try again.
There are now 8 more girls than boys, so you know there are 32 pupils in the class.
You can put this solution on YOUR website! Assume that boys are x then the girls are x+8. since their ratio is 3/5 we write:
solving this equation for x different then 8 we get:
The boys are 12 and the girls 12+8=20.
