A grapefruit is 8% heavier than an orange, and an apple is 10% lighter than the orange.

By what percentage is the apple lighter than the grapefruit?
Answered by Reiny
g = 1.08 o -----> o = g/1.08

a = .9 o ---> o = a/.9

g/1.08 = a/.9
.9 g = 1.08a
a = (.9/1.08) g
a = .8333... g

state your conclusion.

Grapefruit=108
Orange=100
Apple=90

a) (108-90)/90*100 = 18/90*100=20%
