To subtract fractions, we need to have a common denominator. The common denominator for 3 and 5 is 15.
-2/3 can be rewritten as -10/15 (multiplying numerator and denominator by 5).
3/5 can be rewritten as 9/15 (multiplying numerator and denominator by 3).
Now, we can subtract the fractions:
-10/15 - 9/15 = -19/15
Therefore, -2/3 - 3/5 = -19/15.
