If there are 12 boys and 30 girls in a room, fill out all of the possible ratios of boys to girls that could be made.

Question

12:30

6:15

2:5

Answer 1

The three possible ratios are given.

Answer 2

I guess you could say that 8:20 was a possible ratio, or perhaps 1200:3000.

So I guess the set of all possible ratios is 2x:5x where x is any real number. Although since we are dealing with students perhaps it makes sense to restrict x to whole numbers.
