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

20 -4 { 20÷ 7 ( 7 - 3 )}
20 -4 { 20 ÷ 7 * 4 }
20 - 4 { 2.85 * 4 }
