Answer:

[tex]\frac{23}{12}[/tex]

Step-by-step explanation:

Start by making a common denominator. In this case, it would be 12.

Multiply -1/3 by 4 to get -4/12

Multiply -9/4 by 3 to get -27/12

Then subtract

- [tex]\frac{4}{12}[/tex] - (- [tex]\frac{27}{12}[/tex] ) =23/12

You can also visualize this on a number line. Once you've made the denominator the same, start at -4/12 and move 27 units to the left to land on 23/12.
