The question is as follows: "In a group of 48 children, the ratio of boys to girls is 3:5. How many boys must join the group to make the ratio of boys to girls 5:3."
I know the current number of boys to girls is 18:30 and that the number of girls should stay the same. But I don't know how to get the number of boys that have to join, how would you do it without guess and check?
