Proportion:
200 / 180 = 250 / x
Cross multiply:
200 x = 180 ∙ 250
200 x = 45 000
x = 45 000 / 200 = 225 pounds
OR
weighs on Venus / weighs on Earth = 180 / 200 = 0.9
x = 0.9 ∙ 250 pounds = 225 pounds
200 / 180 = 250 / x
Cross multiply:
200 x = 180 ∙ 250
200 x = 45 000
x = 45 000 / 200 = 225 pounds
OR
weighs on Venus / weighs on Earth = 180 / 200 = 0.9
x = 0.9 ∙ 250 pounds = 225 pounds
