To print a telephone book,565 sheets of paper were used. if the book is 2.6 inches thick, what is the thickness of each sheet of paper.? round to the nearest thousandth of an inch.

You divide the width of the book by the number of sheets of paper in order to get the thickness of each of the pieces of paper.

The telephone book is 2.6 inches thick, with 565 sheets of paper.

What this means is 2.6 inches is the thickness of 565 sheets of paper.

To find the thickness of each sheet of paper, all we do is:

2.6 ÷ 565

This gives us quite a large

0.0046017699

To round to the thousandth place, we look at the third number past the decimal and look to see if we need to round up or round down.
The number to the right of our digit in the thousandth place lets us know (in this case) to round up.

Therefore, 0.0046017699 rounded to the nearest thousandth is:

0.005
Don't forget to label (inches)
