Aye, Khan Academy person, too :3

Okay so here's what I got:

Khan wants you to just add them. First, you should change the plus negative to a minus sign:

-5/9 - 7/12

Then, convert the fractions to have alike denominators:

-5/9 = -60/108

7/12 = 63/108

Now, you can subtract easily:

-5/9 - 7/12 = -41/36

As a mixed number: -1 5/36

Hope this helps :3
