Question

Chad tracked the number of children and adults that came in over am a hour. During that time, 8 children and 20 adults came in the restaurant. What is the ratio of adults to children that came in the restaurant

Answer 1

We can write the ratio of a to b like this:

$a\text{ to b}\equiv a\colon b\equiv\frac{a}{b}$

then, if there were 8 children and 20 adults, the ratio of adults to children is:

$\begin{gathered} \text{adults to children:} \\ 20\colon8\equiv\frac{20}{8}=\frac{5}{2}\equiv5\colon2 \end{gathered}$

therefore, the ratio of adults to children is 5:2
