1.2 x 120 = 100
f = 100
f 120 = 1.2 / ∗ f f = 0 120 = 1.2 f / ∗ 10 120 ∗ 10 = 1.2 ∗ 10 ∗ f 1200 = 12 f / : 12 f = 12 1200 f = 100
To solve f 120 = 1.2 , multiply both sides by f to get 120 = 1.2 f . Then, divide both sides by 1.2 , leading to f = 100 . This means that the variable f is equal to 100.
