Answer:

Step-by-step explanation:
First we need to change the mixed numbers into improper fractions.
9 x 10 = 90 + 1 = 91/10
4 x 4 = 16 + 3 = 19/4
Now we need to get them into simplest terms. There is a few ways to do this, but I know that 10 x 2 = 20 and 4 x 5 = 20 so I will use 20.


Now we can subtract:

And that leaves us with our answer :D
