Question

A math book is .78 centimeters thick. What is the width of 21 math books on a shelf?

That's an awfully slim math book. Are you sure it's only 0.78 cm thick?

0.78 * 21 = 16.38 cm

Answer 2

This is so easy and I'm a fourth grader.


All you have to do TJ is to multiply 78 by 21

If you ever get a question that says a piece of information and then asks how many, what width, what number, etc. would blank be you are multiplying.

Piece of info: One book is .78 cm wide.
