Here are the steps:

1. The denometer is not the same. So, find the same denometer to make the problem proper.

-4/3-4/5 = -20/15-12/15 = 

2. Then, find the answer.

-20/15 - 12/15 = -32/15

3. (Here comes the simplifying) Simplify using division. divide -32 by 16

-32/16 = -2 2/15

For the second one:

1. You have to multiply straight across

2/3 x 22/33 = 44/99

2. Simplify.

44/99 = 0.44
