    Answer: 1.25 litres

    Step-by-step explanation:

    Two litres of paint is sufficient to paint  1 ⅗  doors.

    To find out the amount of paint needed to paint one door, you can use direct proportion:

    2 litres           :              1 ⅗  door

    x                                    1 door

    Cross multiply to get:

    1 ⅗ x = 2

    x = 2 /  1 ⅗

    x = 2 ÷ 8/5

    x = 2 * 5/8

    x = 1.25 litres
