Question

One diet uses a ratio of 9:5:4 for carbohydrates, protein, and fat. A nutritionist is developing a diet that provides 450 calories from protein per day. Find the number of calories that should come from carbohydrates

Answer 1

Answer:

There are 810 calories from carbohydrates

Step-by-step explanation:

carbohydrates: protein:  fat

9                       :5           :4                  

We want 450 calories from protein

450 /5 =90

Multiply each term by 90

carbohydrates: protein:  fat

9*90                  :5*90   :4*90

810                        450      360

There are 810 calories from carbohydrates

Answer 2

Answer:

810 calories are carbohydrates

Step-by-step explanation:

We know that the ratio 9:5:4 tells us that 18 equal amounts' of calories make up a meal. Now we know that 450 calories equals 5 of this parts (since protein is made out of 5 of this parts. Now we have to find out the amoung of calories in one of this 18 parts and multiply it by 9. So we do......

450 / 5 = 90

90 x 9 = 810
