Answer:

A: 238.455 L

B: 120 containers

Step-by-step explanation:

A:

31.5 × 2 = 63 gallons

63 gallons = 3.785 × 63 = 238.455 L

B:

because we want to pour 238.455L oil into 2L containers,we can do this:

238.455 ÷ 2 = 119...0.455

we can pour the oil into 119 containers,but there is still 0.455L oil.

So,we need one more containers for 0.455L oil.

119 + 1 = 120 containers.
