    Answer:5/3 litres of paint is needed for 1 door.

    Step-by-step explanation:

    All the doors that Maren is painting are of the same size.

    She used 3 liters of paint to cover 1 4/5 doors. Converting 1 4/5 into improper fraction, it becomes 9/5.

    Let the number of litres of paint needed to paint 1 door would be x. Therefore

    3 litres = 9/5 doors

    x litres = 1 door

    Crossmultiplying, it becomes

    3 * 1 = x * 9/5

    3 = 9x/5

    9x = 3 * 5 = 15

    x = 15/9 = 5/3 litres
