Question

The weight V of an object on Venus varies directly as its weight  E on earth. A person weighing 100lb on earth would weigh 83.8 LB on Venus. How much would a person weighing 180lb on earth weigh on Venus? 

Answer 1

150.84 pounds

ratio of weight on Venus to weight on earth remains the same

83.8/100 = V/180 multiply by 20

83.8/5 = V/9 cross multiply

5V = 9(83.8) divide by 5

V = 9(16.76) = 150.84 lbs. on Venus if they weigh 180 on earth
