Nutritionists help people plan diets to improve their health.
Some diets are based on a ratio of different types of nutrients.
The ratio depends on the goal of the diet. One diet uses a ratio of
9:6:5 for carbohydrates, protein, and fat.
A nutritionist is developing a diet that provides 450 calories
from protein per day. Based on the nutrition ratio above, how
many calories should come from carbohydrates and how many
calories should come from fat?
