To subtract the given numbers, we need to borrow from the whole number and convert the fractions into a common denominator.

18 3/8 = 17 11/16 and 6 15/16 = 6 15/16.

Now we can subtract the numbers:

17 11/16 - 6 15/16 = (17 - 6) + (11/16 - 15/16) = 11 + (-4/16) = 11 - 1/4 = 11 - 4/16 = 11 - 1/4 = 11 - 1/4 = 11 5/16

Therefore, the answer is 11 5/16.
