Answer: +4/3
Explanation: It's important to understand that dividing by a fraction
means the same thing as multiplying by the reciprocal of that fraction.
In other words, we can simply change the division symbol
to multiplication and flip the second fraction.
So we can rewrite this problem as -2/3 · -2/1.
We can't cross-cancel anything.
Before multiplying, take note of your signs.
A negative times a negative is a positive,
so we know that our answer will be positive.
Multiplying across the numerators and denominators, we have +4/3.
