r = red peppers
g = green peppers
The ratio of red and green peppers in a truck is 3:4 means:
r / g = 3 / 4
The truck contains 120 green peppers means:
g = 120
Put this value in ratio:
r / g = 3 / 4
r / 120 = 3 / 4
Multiply both sides by 120
r = 120 ∙ 3 / 4 = 360 / 4 = 90
90 red peppers
Proof:
r / g = 90 / 120 = 30 ∙ 3 / 30 ∙ 4 = 3 / 4
g = green peppers
