Question

A pineapple is 7 times as heavy as an orange. the pineapple also weighs 870 grams more than the orange.

a.what is the total weight in grams for the pineapple and orange?
b.express the total weight of the pineapple and orange in kilograms.

Answer 1

p = 7o

p = o + 870

o + 870 = 7o
870 = 7o - o
870 = 6o
870/6 = o
145 = o

p = o + 870
p = 145 + 870
p = 1015

total weight of pineapple (p) and orange (o) = 1015 + 145 = 1160 grams

1 gram = 0.001 kg...so 1160 grams = (1160 * 0.001) = 1.16 kg
