Q. 584Chapter 7 Rational Expressions and Equations23. Andrew is on a low-carbohydrate diet. If his diet book tells him that an 8 -oz serving of pineapple contains 19.2g of carbohydrate, how many grams of carbohydrate does a 5-oz serving contain?
Calculate Carbs per Ounce: We need to find out how many grams of carbs are in 1oz first, so we divide the carbs in the 8-oz serving by 8. 19.2g÷8oz=2.4g per oz.
Multiply Carbs for 5 Ounces: Now we multiply the carbs per oz by the number of oz in the serving we want, which is 5 oz.2.4g/oz×5oz=12g.
