Answer:
number of servings = 5 servings
Explanation:
We are given that each serving is 3/10 of a pint. To know the number of servings of 1.5 pints, we will simply use cross multiplication as follows:
1 serving ....................> 3/10 pint
?? servings ................> 1.5 pints
number of servings = (1.5*1) / (3/10)
number of servings = 5 servings
