There was 5 L of juice on the table. Ryan drank 1 of the juice. Students can use the diagram below to help
5 them understand the guided practice
problem.
Kate drank 1 of the remaining juice. How many liters of juice are left?
3 5L

The amount of juice can be expressed as, 1. Ryan drank 1 of the juice. 4L
5

The remaining amount of the juice can be expressed as ·1 1 ‚.
5

3 ·1_ 1 ‚.

So, the amount of juice left (in liters) is 5

5 ·1 1 ‚ = 5 4 4 2 8 2 2 L
5 3 3 3
5 = 4 liters

The amount of juice left after Ryan can be expressed as, 1. Kate drank 1 of it.

The remaining amount of juice can be expressed as ·1 3 ‚.

So, the amount of juice left (in liters) is 4 ·1 1 ‚. 2. Have the students use the guided practice
3 problem to solve problem 2.

4 ·1 1 ‚ = 4 28 2 If students are having trouble solving this

2 problem, have them look at the diagram

So, 2 3 L of juice are left after Kate. below to guide them to the solution.

Refer to .

2 . Solve the problem using the method above.

a. There was 3 1 L of water. Jessica drank 3 of the water. Ann drank

1 ·1 3 1 L of water are left after
Amount of water left after Jessica: 3 2 7 ‚ = 2 1 4 Ann.

Amount of water left after Ann: 2 ·1 3 ‚ = 5 = 1 1
