6 For every 3 girls in Mr Hegarty's class there are 5 boys. What is the ratio of girls to boys in the class? Give your answer in its simplest form.

We cannot simplify this further because 3 and 5 have no factors in common, other than 1. So we just leave it as is.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
