24

18(4/3)=24

To find out how many math textbooks can be placed standing up on a shelf that is 18 inches wide, we need to divide the width of the shelf (18 inches) by the width of each textbook (0.75 inches).

Dividing 18 inches by 0.75 inches gives us:

18 / 0.75 = 24

Therefore, you can place 24 math textbooks standing up on a shelf that is 18 inches wide.
