Work Step by Step
Left-handed females are $\text{L-h females }=1332$. Left-handed females are $15 \%$ of all females. The total amount of females is
$$\text{Females} = \text{L-h females } \dfrac{100\%}{15\%}=1332 \dfrac{100\%}{15\%}=8 880.$$
Females are $48\%$ of the community. So the total amount of people:
$$\text{People} = \text{Females}\dfrac{100\%}{48\%}=8880\dfrac{100\%}{48\%}=18 500.$$
