The rate per cent. is a fraction whose denominator is 100 and whose numerator is the given number of hundredths; thus 6% of a number is 6/100 of that number. The method of figuring the per cent. of foodstuffs in a food material is simple. Milk, for example, has a percentage composition of 3% protein, 4% fat, and 5% sugar. To find the definite amounts of these foodstuffs in 1 ounce of milk it is best to reduce the ounce to grams, since the gram is the unit of measurement generally used. 1 ounce = 28.35 grams In 1 oz. there will be 28.35 x .03 = 0.85 gram protein In 1 oz. there will be 28.35 x .04 = 1.13 grams fat In 1 oz. there will be 28.35 x .05 = 1.41 grams sugar THERMOMETRY
