Answer:
The unit rate is 5.33 grams per serving.
Explanation:
In this problem, we have to find the unit rate, that is, the number of grams per serving.
To find the answer, we can use the rule of three:
If 4 grams are equivalent to 3/4 serving, how much grams would be equivalent to 1 serving.
![1 \ serving (4 \ grams)/((3)/(4) \ serving ) =(16)/(3) \ grams = 5.33 \ grams](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7cmbmqn3mfw8up04rnfk2rb3b6thlvnq4q.png)
Therefore, the unit rate is 5.33 grams per serving, approximately.
