a) original = 9 micrograms

(i) Percentage change = 70

(ii) Number multiplied = 30/100 = 0.3

(iii) New intake amount = 9 X 0.3 = 2.7

b) original = 1100 micrograms

(i) Percentage change = 116

(ii) Number multiplied = 216/100 = 2.16

(iii) New intake amount = 1100 X 2.16 = 2376

c)original = 46 micrograms

(i) Percentage change = 12

(ii) Number multiplied = 88/100 = 0.88

(iii) New intake amount = 46 X 0.88 = 40.48

d) original = 640 micrograms

(i) Percentage change = 37
