Answer
There are 448 cans in 112 four-packs, and 17 four-packs are necessary to reach 68 cans.
Work Step by Step
1. If each four-pack has 4 cans.
$$112 \ four-packs \times \frac{4 \ cans}{1 \ four-packs} =448 \ cans $$
2. Using the same logic:
$$68 \ cans \times \frac{1 \ four-packs}{4 \ cans} =17 \ four-packs $$
