If Roger can use the bowl, he needs to determine how many liters of liquid could still fit into the bowl. If he cannot use the bowl, he needs to determine how many extra liters of liquid there are. Round your answers to the nearest tenth of a liter. Show your work.

To determine how many liters of liquid could still fit into the bowl, we need to know the capacity of the bowl and the amount of liquid currently in it. Let's denote the capacity of the bowl as C liters and the amount of liquid currently in it as L liters.

If Roger can use the bowl, the amount of liquid that could still fit into the bowl is equal to the difference between the capacity and the current amount of liquid.
Liquid that could still fit into the bowl = C - L

If Roger cannot use the bowl, there are extra liters of liquid. The amount of extra liquid is equal to the current amount of liquid minus the capacity of the bowl.
Extra liters of liquid = L - C

For example, if the capacity of the bowl is 5 liters and there are currently 3.5 liters of liquid in it, then:
Liquid that could still fit into the bowl = 5 - 3.5 = 1.5 liters

If the capacity of the bowl is 5 liters and there are currently 6 liters of liquid in it, then:
Extra liters of liquid = 6 - 5 = 1 liter

Remember to round the answers to the nearest tenth of a liter.
