Question

A bookshelf at a library is 4 feet 1 inch. There are 14 copies of the same book onthe shelf, which it the shelf exactly. What is the width of the books?A 3 1/2 inchesB. 3 inchesC3 9/12 inchesD. 34/12 inches

Answer 1

First let's convert from feet to inches.

Each feet corresponds to 12 inches, so we have:

$4\text{ feet 1 inch}\to4\cdot12+1\text{ inches}\to48+1\text{ inches}\to49\text{ inches}$

Now, dividing the total width by the number of books, we have:

$\frac{49}{14}=\frac{42+7}{14}=3+\frac{7}{14}=3\frac{1}{2}$

So the width of each book is 3 1/2 inches, therefore the answer is A.
