Ivory's mass compared to Will's mass in percent
= 100% + 50%
= 150%
Shannon's mass compared to Will's mass in percent
= 100% - 25%
= 75%

34Will's mass is the repeated identity. Make Will's mass the same.
Will's mass = 4 u
Mass that Ivory has more than Shannon
= 6 u - 3 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Will's mass
= 4 u
= 4 x 3
= 12 kg
Answer(s): 12 kg
