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:
[tex]\text{Number of children = }\frac{ratio\text{ of chil}ldren}{\text{total ratio}}\times\text{total number of people}[/tex]
Where:
Ratio of children = 3
Total ratio = 12 + 3 = 15
Thus, we have:
[tex]\begin{gathered} \text{Number of children=}\frac{3}{15}\times90 \\ \\ \text{Number of children}=0.2\times90=18 \end{gathered}[/tex]
Therefore, the number of children in the park is 18 .
ANSWER:
18
