11.5 can be expressed aloud as "eleven and a half" therefore the most obvious units to use to express it as a fraction would be multiples of a half. There are 22 "halfs" in 11 and one more from the .5, so it is most easily expressed as 23/2 or aloud as "23 halves". It should be noted that it could just as easily be expressed with many other denominators (the number on the bottom of a fraction). For example, you could call it 46/4 or "46 fourths" or 92/8 (92 eigths) and so on.
