[tex]\textrm{Percentage = Base × Rate}[/tex]
[tex]\textrm{Percentage = 15 000 × 0.28}[/tex]
[tex]\textrm{Percentage = 4200}[/tex]
We solved that 4200 are children. Thus we will subtract it to the total of populations.
[tex]\textrm{15 000 - 4200 = not children}[/tex]
[tex]\textrm{10 800= not children}[/tex]
[tex] \large\underline{ \bold{ANSWER}}[/tex]
- The number of not children from the population is 10 800.
