Answer:

-7/9

Explanation:

-3 1/9 - -2 1/3

Subtracting a negative is adding

-3 1/9 +2 1/3

We need to get a common denominator of 9 1/3 *3/3 = 3/9

-3 1/9 + 2 3/9

These have opposite signs, so we subtract the smaller from the larger and take the sign of the larger

3 1/9 - 2 3/9

We have to borrow from the 3 because the fraction is not large enough 3/9 is larger than 1/9

The 3 becomes a 2 and 1/9 becomes 1/9 + 9/9 = 10/9

2 10/9 - 2 3/9 = 7/9

We take the sign on 3 /19 which was negative

-7/9
