Outlined on the checkered paper is a rectangle of 7 × 9 cells. What is the maximum number of 5 × 1 cell stripes you can cut out of it?

I'm not sure but I assume you will see how many times 5 can go into 63 so ince you get that (which u can google) you should have an answer!

90 = 3x

x = 90/3

x = 30

so:
