1. -4
2. 4
3. -15
4. 15

Explanations:
A negative times a positive gives a negative product. A negative times a negative gives a positive product.

1. Multiply -12×1, = -12, then divide by 3 = -4
2. Multiply -12 x -1, = 12, then divide by 3 = 4
3. Multiply 12 x -5, = -60, then divide by 4 = -15
4. Multiply -12 x -5 = 60, then divide by 4 = 15

When you’re dealing with fractions, the negative applies to the whole fraction, but you only use it once. Like, you would use it for this multiplication, but not the division. I hope that helps.
