Question

Rewrite 3/9 as a mixed number

Answer 1

3/9 is already a fraction, you do not need to change it. 3/9 is not more than 9/9

Answer 2

1/9 + 2/9 = 3/9
                                                                                                                            because when you add 1 and 2 you will get 3 and you will keep the 9 the same
