ANSWER

It takes 16 minutes for 9 people to paint 8 walls. How many minutes does it take 4 people to paint 6 walls?

This is a ratio problem that I'm stuck on.

I know it will take 1/8 of the time to paint one wall. I don't understand how everyone figures out that for only one person, it will take 9 times as long.

Then they say it will take 2 x 9= 18 minutes for one person to paint one wall. I don't know where the 2 x 9 comes from?

In the end they say the number of minutes it will take for one person to paint 6 walls is 18 x 6 = 108

The number of minutes it will take for 4 people to paint 6 walls is 108 ÷ 4 = 27. The answer is 27, but what I need is a for dummies explanation on how it became 27.
