Answer 1

We know that the problem that 15% of the toddlers equals 3 toddlers. Whit that information we can establish a proportion like follows:
If 15% of the toddlers are 3 toddlers, 100% of the toddlers are
`x` toddlers:

`(15----\ \textgreater \ 3)/(100---\ \textgreater \ x)`

`(15)/(100) = (3)/(x)`

`x= ((100)(3))/(15)`

`x= (300)/(15)`

`x=20`

We can conclude that there are a total of 20 toddlers in the preschool class.
