Answer:
This is not possible without a whole number turned into a fraction. So I guess -1/5 x 3/1 OR -3/5 x 5/5 would work.
Explanation:
1 fraction must be negative and 1 must be positive to get a positive answer. I found out that -1/5 and 3/1 would work, though 3/1 is a whole number. Later, I found out that -3/5 and 5/5 would work, though 5/5 is still a whole number when converted. I don't think this problem is possible without a whole number.
