To subtract in Roman numerals, you simply place a smaller number in front of a larger one. You subtract the value of the smaller number from the larger one. For example, to express 4 in Roman numerals, you write IV (5-1). Similarly, to express 9, you write IX (10-1).

x - (y + 2)
When you subtract 16 2/3 from 7 7/8 you will get 211/24 as a mixed number.

If you subtract 5 from 2, you get negative 3 (-3).
Instead of "a half", write "eight sixteenths". That doesn't change the value of any numbers, but it makes it a lot easier to subtract the three sixteenths from the eight sixteenths.
