To combine like terms, we first need to simplify the expressions:
1/3a + 3/4a = 4/12a + 9/12a = 13/12a
-2/5b - 4/15b = -6/15b - 4/15b = -10/15b = -2/3b
Now combining the simplified expressions:
1/3a - 2/5b + 3/4a - 4/15b = 13/12a - 2/3b
To combine like terms, we first need to simplify the expressions:
