You need to find a common denominator.
Multiply -3/8 times 9/9 to get -27/72.
Multiply -5/9 times 8/8 to get -40/72.
Rewrite the equation:
-27/72 -(-40/72)
Subtracting a negative is the same as adding a positive:
-27/72 + 40/72 = 13/72
Since 13 is a prime number, it has no factors and this fraction can't be reduced.
