Do you brought a cooler container 7.5 L of water to the picnic in 500milliliters of the water I serve to each person and how man
Dafna11 [192]

Answer:

15 people will be served before the cooler would be empty

Step-by-step explanation:

Here, we want to know the number of persons that could be served if the total amount of water available is 7.5L and each serving is 500 milliliters

What we are going to do here is to divide the total amount of water available by the number of individual servings

Mathematically, that would be;

7.5L / 500 milliliters

So we need to convert 7.5L to milliliters

Since 1000 mL = 1L ; 7.5 L = 7.5 * 1000 = 7500 mL

So the number of people served will be;

7500/500 = 15 people
