Question

You paint 13 of a wall in 14 hour. At that rate, how long will it take you to paint one wall?

Answer 1

it will take 3/4 hours

Answer 2

I assume you mean 1/13 of a wall.

This means in 14 hours you paint one piece of a wall that is divided equally into 13 sections. If we paint all 13 of those sections, we get that 13 * 14 = 13 * 10 + 4*13 = 130 + 52 = 182 hours.
