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?

1 Can of Paint to Paint 1/18 of their house.

1/18 of house paint by 1 can

1 of house Paint by 18 can

4/9 of "     "     " = 18 * 4/9 = 8 can

5/6 "         "     " = 18 * 5/6 = 15 can

They buy total (8 + 15) can of paint

But it's required 18 can to paint the

whole house.

They should return = (23 - 18) = 5 can

5 can they should return to the store.
