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 [tex]x[/tex] toddlers:
[tex] \frac{15----\ \textgreater \ 3}{100---\ \textgreater \ x} [/tex]
[tex] \frac{15}{100} = \frac{3}{x} [/tex]
[tex]x= \frac{(100)(3)}{15} [/tex]
[tex]x= \frac{300}{15} [/tex]
[tex]x=20[/tex]
We can conclude that there are a total of 20 toddlers in the preschool class.
