Explanation:
We have been given that the United States has 435 members of the House of Representatives in Congress. There are 325.7 million people in the country.
To find the ratio of members to the people, we will find compare both numbers.
1 million equals 1,000,000.
![\text{325.7 million}=325.7* 1,000,000](https://img.qammunity.org/2020/formulas/mathematics/college/pm3j5497l5franr2m3itahh03u5qap8d9e.png)
![\text{325.7 million}=3257,000,000](https://img.qammunity.org/2020/formulas/mathematics/college/tn09fbhng5o52436mrto4w8dfafgse3txp.png)
Ratio of members to the people:
435: 3257,000,000
![0.0000013355848941:1](https://img.qammunity.org/2020/formulas/mathematics/college/83dg521wnr27204lju6393xh1x8t1pnt5v.png)
![1.3355848941* 10^(-6):1](https://img.qammunity.org/2020/formulas/mathematics/college/534cl84sjuu1eq1jwu5j4h2d3miz9af1nf.png)

Therefore, our required ratio would be
members per person.
