Question

Eric's car has a gas tank that holds 21 liters. If Eric used up 2 decaliters of gas, how many liters of gas does he have left in the tank?

2 Answer

  • 2 decaliters is equal to 20 liters. 21-20=1. 
  • Capacity of the gas tank = 21 liters.

    Amount of gas used by Eric = 2 decaliters

                                                  = 2 × 10

                                                  = 20 liters

    To find the amount of gas left in the tank, we have to subtract 20 from 21.

    So, amount of gas left in the tank = 21 - 20

    = 1 liter.
