Multiple: 45 * (-3) = 4 · (-3)5 · 1 = -125 = -2.4 · 51 · 5
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-12, 5) = 5

Divide: -125 : 4 = -125 · 14 = -12 · 15 · 4 = -1220 = -35
To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

4 x -3 is -12 and 5 x 4 = 20 so its -12/20
