In the US House of Representatives, about 12.2% of the representatives are from the state of California. If there are 435 representatives, how many are not from California?

A.12.2

B.53

C.382

D.488

【答案解析】

答案：C

解析：

Choice C is correct. Use the variable r to represent the number of representatives from California, set up an equation to determine how many representatives are from California.

(0.122)(435)=r, and so r=53.07

There are 53 representatives from California.

To find the number of representatives not from California, subtract the number of representatives from California from the total number of representatives.

435-53=382

Therefore, 382 of the representatives are not from California.
