Question

The printed label from a container of milk is shown below. 1 GAL(3.78L) How many 210-milliliter servings are in the container? round to the nearest whole number. servings

Answer 1

First convert 3.87L to ml. There are 1000ml in 1 L.  We need L on the top left and bottom right so they cancel

 

3.87L        1000ml

--------- x    -----------

    1                  1L

 

Liters cancel and we can multiply to get:

3870ml in the 1 gal container.

We need to know how many 210ml servings are in the 1 gal container so we divie 3870ml by 210ml

3870ml/210ml servings= 18.428 servings

Round to the nearest whole number.  Since the tenths place is below 5 we round down to:

18 servings
