Answer:

$2\frac{1}{4} \ inch$

Step-by-step explanation:

We have the four thickest books from the line plot given by

Two books of $\frac{1}{2}$ inch thick and the two books of $\frac{5}{8}$ inch thickness.

So when the two $\frac{1}{2}$ inch thick book is being piled on the top of a $\frac{5}{8}$ inch thick books.

Therefore, the total thickness of the pile of books is given by :

$=2 \times \frac{1}{2}+2 \times \frac{5}{8}$

$=\frac{9}{4}$

$=2\frac{1}{4} \ inch$

Therefore, the thickness of the pile is $2\frac{1}{4} \ inch$ .
