100 x = 3 8 ⇒ x= 3 100 ∗ 8 = 3 800 = 266 , ( 6 )
if 8 = 3 (consider 8 to be and 3 to be earth (proportional)) then x = 100 (cross multiply) x × 3 = 8 × 100 3x = 800 3x /3 = 800 / 3 x = 266.67 (this rounded to two decimal places) therefore a person who weighs 100 pounds on earth would weigh 266.67 on jupiter
A 100-pound person would weigh approximately 266.67 pounds on Jupiter based on the 8 to 3 weight ratio. This is calculated by using the formula W j = W e × 3 8 . Jupiter's stronger gravity causes the increase in weight.
