When you divide fractions, you keep change flip. So in the end you're multiplying. To solve, just find what times is 1 and what times what is 3? For example, 1 times 1 is one, and 1 times 3 is 3. The fraction would be 1/3 times 1/1. Since you flip the second one to solve, the answer would be 1/3 times 1.
