Question

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 3/5 doors. How many liters of paint are nedded for 1 door? Draw a diagran to represent the situation.

Answer 1

`1(3)/(5)=(8)/(5)`

so we have that to paint 1 door we have to use:

`(2)/((8)/(5))=2\cdot(5)/(8)=(5)/(4)=1(1)/(4)`

so we have to use 1 1/4 liter to paint one door
