Given:
The population of Greens County is,
![P=2.4*10^6](https://img.qammunity.org/2023/formulas/mathematics/college/21exn9i7vqtpvf0grb1and4zmm83mcvvzy.png)
The population of Brownsville is
![p=800,000](https://img.qammunity.org/2023/formulas/mathematics/college/5fjmv3m1aqr2ukek8677qkmqfta6jwjobv.png)
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.
![\begin{gathered} (P)/(p)=(2.4*10^6)/(800000) \\ (P)/(p)=(2.4*1000000)/(800000) \\ (P)/(p)=(2400000)/(800000) \\ (P)/(p)=3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/orlb8xslvh2yn0kn9vswf8lcigfkd221ke.png)
Therefore,
![P=3p](https://img.qammunity.org/2023/formulas/mathematics/college/4job8c9gv3d29ztv614ehvpdtf2z2284bn.png)
Hence, the poulation of Greens County's is 3 times larger than Brownsville's.
Answer: 3
