Question

Clare is painting some doors that are all the same size. She used 7 liters of paint to cover 812 doors. How many liters of paint are needed for 1 door?

Answer 1

It would take 1/116 of a liter.

Explanation:

If you take 812/7.. You get 116. You then know thats one liter of paint. But you dont want to know what one liter is. You need to know what one door is. So you make that 1/116 which is one door out of the 116 doors in that one liter of paint. Hope this helps.
