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
