How Much Liquid?

The following amounts of juice were left in separate containers after the school’s parent breakfast.

●      Container 1:  750 mL

●      Container 2:  1,450 mL

●      Container 3:  2 L

●      Container 4:  299 mL

●      Container 5:  476 mL

 a)     If all of the liquid was put into one large container, how much liquid would be in the large container?  (4,975 mL)

b)    The large container can hold 5 Liters.  How much room is left in the container? Write an equation to match your thinking.  (5,000 mL – 4,975 mL = 25 mL)

Write an explanation about how you solved this problem.  (Explanations will vary.)
