Ratio of cheese to pepperoni...
45 cheese....20 pepperoni.....45/20 reduces to 9/4 or 9:4

little tip ** be careful of the wording of problems such as these.....because if it asked for the ratio of pepperoni to cheese, it would have been 4:9

Micheal has 40ft of fencing for the rectangular dog run. So the perimeter of the dog run is 40ft.

Perimeter=40ft

The perimeter of a rectangle is:

P=2l+2w

Since we know the length is 5 and the perimeter is 40, we can solve for the width.

P=2l+2w
40=2*(5)+2w
40=10+2w
subtract 10 from both sides
30=2w
divide both sides by 2
15=w

The width of the fence is 15feet.
