How to solve 7 (4*1/2) + 3 (5*1/3) + 2 (-3*1/2

Multiple: 4 * 1 / 2 = 4 · 1 = 4 / 2 = 2 · 2

1 · 2 1 · 2 = 2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (4, 2) = 2

Multiple: 7 * 2 = 14

Multiple: 5 * 1 / 3 = 5 · 1

1 · 3 = 5 / 3

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (5, 3) = 1

Multiple: 3 * 5 / 3 = 3 · 5

1 · 3 = 15 / 3 = 5 · 3

1 · 3 = 5

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (15, 3) = 3

Add: 14 + 5 = 19

Multiple: - 3 * 1 / 2 = - 3 · 1

1 · 2 = - 3 / 2 = - 1.5 · 2

1 · 2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (-3, 2) = 2

Multiple: 1/2 * (-3 / 2) = 2 · (-3)

1 · 2 = - 6 / 2 = - 3 · 2

1 · 2 = - 3

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (-6, 2) = 2

Add: 19 + (-3) = 16

7 (4*1/2) + 3 (5*1/3) + 2 (-3*1/2) = 16 / 1 = 16
