Question

In a breakfast cereal, 40% of its weight is fruit.

Answer 1

(a) We have been given that fruit consists of 40%. If the remaining is oats, then oats should be = 100% - 40% = 60%

So, fruit = 40% and oats = 60%

Ratio of weight of fruit : weight of oats = 40: 60

weight of fruit : weight of oats = 4: 6

Simplifying, weight of fruit : weight of oats = 2:3

(b) Given ratio is weight of fruit: weight of bran = 1: 3

Total weight = 1+ 3 = 4

Since bran is three parts and fruit is only one part,

Fraction of weight of bran = 3/4 = 0.75 = 75%

Answer 2

A 2/5 or 2:3
b 25% or 1/4
im 90% sure this is correct
