A nutritionist recommends that a certain client getof his calories from fats,of his calories from proteins, and the remainder of his calories from carbohydrates.
What fraction of all calories should the client get from carbohydrates?
This problem tests fraction addition and subtraction within a real-world nutrition scenario, which is typical of the NEX Math Section. First, recognize that all calorie fractions must total 1 (or the whole). The client getsfrom fats andfrom proteins. To combine these fractions, find a common denominator. The least common denominator of 5 and 4 is 20. Convert the fractions:and. Add them together:. This represents the portion of calories from fats and proteins combined. To find the remainder from carbohydrates, subtract from 1:
Therefore, the correct answer is B. This type of problem reinforces careful fraction operations and understanding of “remainder” language on the NEX exam.
