Question

Look at the model below.

Which multiplication sentence can be used to calculate the total shaded
area shown in the model?

4 x 1/5
4 x 1/4
5 x 1/5
5 x 1/4

Answer 1

A is the answer!


Explanation:
You have four rectangles, and in each one of them, there is one cube shaded, so instead of you counting all of them, you only do it for one. Also, in each rectangle, there are five cubes and one shaded, so one over five and the four comes from the number of rectangles.
I hope this helps!
