Ineed with starring the answer in mixed fraction

To make a improper fraction you multiply the whole number by the denomination and add it to the numerator. That number is over the denominator that was there before, in this case 9.

-1 2/9 = -11/9
-7/3 - 11/9 -- needs common denominator
-7/3 x 3/3 = -21/9
-21/9 -11/9 = -32/9
To make it back into a mixed number you divide -32 by 9 which equals 3
9x3= 27
32-27= 5---(5 left over)
The answer is either -32/9 or 3 5/9
