A food contains three major ingredients : carbohydrate 50g, fats 15g and proteins 25g.
:
Find total weight: 50 + 15 + 25 = 90g
:
(a) What fraction of food is carbohydrate?
50%2F90 = 5%2F9
:
(b) What percentage of food is carbohydrate?
5%2F9 * 100 = 55.56%
:
(c) What fraction of food is not fat?
%28%2890-15%29%29%2F90 = 75%2F90 = 5%2F6
:
(d) What percentage of food is fat?
15%2F90 * 100 = 16.67%
:
(e) What mass of fat is there in 60g of the food?
.1667 * 60 = 10 grams of fat
