OpenStudy (nottim):

if given that, do you know what to do?

OpenStudy (anonymous):

Is it multiple?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

then, what?

OpenStudy (anonymous):

.17feet * 12inches/feet = 2.04inches which is close to 2 3/16 inches

OpenStudy (anonymous):

How did you get 2 3/16 inches?

OpenStudy (anonymous):

you dont but its the closest answer

OpenStudy (anonymous):

I am sorry, I didn't get what did you say it. "you don't but its the closest answer"?

OpenStudy (anonymous):

Can you explain clearly me?

OpenStudy (anonymous):

Certainly. After doing the math you get 2.04 inches as the answer, and the question asks for which of the following is most closely comparable. That means it's not looking for the exact answer but something close to it. Now because we got 2.04 inches we know the answer can't A, B, or E since those close to 3, 4, and 5 inches which are not close enough to 2 inches. Answers C and D, however, do start with 2 inches so we know it will be close to them. Now the question is which is closer? Well if you did the math C's answer of 2 3/4 is equal to 2.75 in decimals and D's answer is 2.1875. The closest of these to 2.04 is D.
