HELP ME PLEEEEEEAAAASEEEE!

Claire is painting some doors that are all the same size. She uses 3 liters of paint to cover 1 1/5 doors. How many liters of paint are needed for one door?

Answer 1

`2(1)/(2)\ liters`

Explanation:

step 1

Convert mixed number to an improper fraction

`1(1)/(5)=(1*5+1)/(5)=(6)/(5)`

step 2

Using proportion

`(3)/((6/5))(liters)/(doors) =(x)/(1)(liters)/(door)\\ \\x=3/(6/5)\\ \\x=15/6\ liters`

step 3

Convert to mixed number

`(15)/(6)\ liters=(12)/(6)+(3)/(6)=2(1)/(2)\ liters`
