Maren is painting some doors that are all the same size. she used 3 liters of paint to cover 1 4/5 doors. how many liters of paint are needed for 1 door?

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

c. (3,2,6) is the answer.
