Rewrite 31/9 as a mixed number

3 4/9 would be the correct answer

To do this, all you have to do is divide 31 by 9. Doing this will get you the answer 3 with a remainder of 4. And so what you do is put 3 as the whole number while putting the remainder as the numerator of the fraction. Keep the denominator the same, and you'll get the answer 3 4/9.
