+183 John and Julia are repainting the outside of their house. They each go out to buy paint. John buys enough paint to cover \(\frac{4}{9}\) of their house and Julia buys enough to paint \(\frac{5}{6} \) of their house. If it takes 1 can of paint to paint \(\frac{1}{18}\) of their house and they don't want to have any paint left over after they finish painting, how many cans of paint should they return to the store?
