Given:
The population of Greens County is,
[tex]P=2.4\times10^6[/tex]The population of Brownsville is
[tex]p=800,000[/tex]Now, we will find how many times larger is the poulation of Greens County's than Brownsville's.
For that the ratio of the poulations is to be taken.
[tex]\begin{gathered} \frac{P}{p}=\frac{2.4\times10^6}{800000} \\ \frac{P}{p}=\frac{2.4\times1000000}{800000} \\ \frac{P}{p}=\frac{2400000}{800000} \\ \frac{P}{p}=3 \end{gathered}[/tex]Therefore,
[tex]P=3p[/tex]Hence, the poulation of Greens County's is 3 times larger than Brownsville's.
Answer: 3
