Question

Jordan and Ellen recycle cans. Jordan recycles 7 cans for every 12 cans Ellen recycles. Last week, Jordan recycled 42 cans.

What number, c , can be multiplied by 12 to determine the number of cans Ellen recycled last week? How many total cans did Jordan and Ellen recycle last week?

Answer 1

c = 6

Total: 114

Explanation:

The ratio of the number of cans Jordan recycles to the number Ellen recycles is 7:12.

The ratio of the number of cans Ellen recycles to the number of cans Jordan recycles is 12:7.

Jordan recycled 42 cans.

Ellen recycled 42 × 12/7 = 6 × 12

c × 12 = 6 × 12

c = 6

Total: 42 + 72 = 114
