A person drinks 4 cups of fat-free milk in a day and wants to consume 70 per day of protein. What percentage of that protein is obtained from the milk?

Question

Total Fat= 0 grams

Carbs= 13 grams

protein= 9 grams

Answer 1

This is easier than you think and a very good example. (Gildrette has some grammar and spelling errors above, i.e., multiple should be "multiply" and procentage should be "percentage")

We know that 4 cups * 9 grams of protein = 36 grams of protein

36 grams of protein consumed/70 grams wanted per day * 100%

Therefore, 36/70 * 100 = 51.4%

Answer 2

Hi Andre: 

4 cups of milk is equivalent to 9 grams of protein. 

You multiple: 4 cups of milk * 9 grams of protein = 36 grams of protein

The porcentage of protein obtained from the milk is: 36/70 * 100= 51.4%
