A pile of notebooks is 1 1/4 ft. High. Each notebook is 1/2 inch thick. How many notebooks are in the stack?

Question

I think I am supposed to divide but I’m not sure. Please help!

Answer 1

Yes, you are supposed to divide.

divide (the height of the pile) / (thickness of one notebook).

 

remember to convert the height of the pile from feet to inches before dividing, because the thickness of a notebook is expressed in inches.
