1.
The fraction on the left side is a division equation, so the inverse operation would be multiplication.
Multiply both sides by 5:
n/5 = -0.3
n = -0.3 x 5
n = -1.5
2. The equation on the left side is multiplication, the inverse operation would be division. Divide both sides by -2:
n = 4 1/3 / -2
n = -2 1/6
