1. **State the problem:** Add all the given numbers: 13.2, 16, 10.8, 16, 2.7, 14.8, 11.1, 12, 13.2, 9.2, 14.8, 14.8, 16, 16, 14.8, 13.2. 2. **Add the numbers step-by-step:** $$13.2 + 16 = 29.2$$ $$29.2 + 10.8 = 40$$ $$40 + 16 = 56$$ $$56 + 2.7 = 58.7$$ $$58.7 + 14.8 = 73.5$$ $$73.5 + 11.1 = 84.6$$ $$84.6 + 12 = 96.6$$ $$96.6 + 13.2 = 109.8$$ $$109.8 + 9.2 = 119$$ $$119 + 14.8 = 133.8$$ $$133.8 + 14.8 = 148.6$$ $$148.6 + 16 = 164.6$$ $$164.6 + 16 = 180.6$$ $$180.6 + 14.8 = 195.4$$ $$195.4 + 13.2 = 208.6$$ 3. **Final answer:** $$\boxed{208.6}$$ The sum of all the numbers is 208.6.
