3 - 1/9 = 2 + 9/9 - 1/9 = 2 8/9

Just break 3:

3 = 2 + 1 = 2 + 9/9

You let it to be 9/9, so that it has the same denominator as 1/9 , so you could subtract 1/9 from it.

Well 3 - 1/9 = 2 8/9, not 3 8/9

To add or subtract fractions, you need to put them over a common denominator, which should be 9 in this case. To convert 3 into an improper fraction over 9, multiply 3 by 9/9

3 = 3/1 * 9/9 = 27/9

So now we can subtract 1/9 from 3:

27/9 - 1/9 = 26/9 = 18/9 + 8/9 = 2 8/9
