What is 13 an one nineth minus 11 and 2 thirds?

Answer 1

We could convert both mixed numbers to improper fractions with a common denominator or 9, but let's do it the simpler way (or at least easier). 1/9 is less than 2/3, so we borrow 1 from the 13 and get 12 10/9. Then we convert the 2/3 to 6/9 so we have a common denominator. 10/9 - 6/9 is 4/9, and 12 - 11 is 1. So the answer is 1 4/9.
