John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs
to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 140 cans, how many cans of green beans should he use? A. 38 cans B. 40 cans C. 22 cans D. 7 cans
This is a part:part ratio. to solve it we need to convert it into a part:whole ratio. we do this by adding the parts. the ratio of pumpkin cans to total cans is 5:7. 140/7=20. 20x5=100. 20x2=40. The answer is B. 40 cans.
