13% of 160 is 16% of

A. 13
B. 130
C. 1300
D. 13,000

B. 130

Step-by-step explanation:

B - 130

both values are equal to 20.8

Step-by-step explanation:

the first step is figuring out what they want you to compare the multiple choice answers to- 13% of 160, which is equal to 20.8 (160*.13)!

so next, we need to take 16% of each of our answers. we can guess at what our answer isn't going to be, specifically that it cannot be 13 since 20.8 is more than 13. We can also guess its not going to be 13,000, since even ten percent of that is about 130. The same logic can be applied to 1300, ten percent of 1300 (ie dividing 1300 by ten) is 130, again too large.

Therefore, by process of elimination we can guess that its likely B.

As for checking: we have our 20.8 to compare to, and 16% of 130 (.16*130) is in fact 20.8.

16% of 130, or .16*130 is equal to 20.8
