80
XXLL=XXC=80
80 = LXXX or simplified to XXC (100-20) which uses less numerals
XX=20 CC=200 IV=4 but a letter with a lower value can only be written ONCE before a letter of greater value. Thus XXCCIV if written as one numeral is not allowed. XXC (100-20) would mean 80 but 80 can be written correctly as LXXX (50+30).
The Roman numerals for 50 to 80 are: 50 - L 60 - LX 70 - LXX 80 - LXXX

dont worry about it
80 cannot be simplified further.
80 written as a percent = 8000% 80 * 100% = 8000%
7.9 = 79/10
80/231 cannot be simplified.
