Given:

• Ratio of adults to children = 12 : 3

,

• Total number of people = 90

Let's find the number of children in the park.

To find the number of children, apply the formula:


\text{Number of children = }\frac{ratio\text{ of chil}ldren}{\text{total ratio}}*\text{total number of people}

Where:

Ratio of children = 3

Total ratio = 12 + 3 = 15

Thus, we have:


\begin{gathered} \text{Number of children=}(3)/(15)*90 \\ \\ \text{Number of children}=0.2*90=18 \end{gathered}

Therefore, the number of children in the park is 18 .

18
