The equivalent prime numbers from 1 to 10 in Roman numerals are: II, III, V and VII

MCMLXXIII = 1000 + (1000 - 100) + 50 + 10 + 10 + 1 + 1 + 1 = 1973.
12 is written as XII (10 + 1 + 1) in Roman numerals.
I believe it is 27 by Medieval Roman numerologyImproved Answer:-In Roman numerals X = 10 and S = 1/2So XSS = 10+1/2+1/2 = 11
CLXIII(ie. 100 + 50 + 10 + 1 + 1 + 1)
The roman numerals for 1-10 are as follows:IIIIIIIVVVIVIIVIIIIXX
Arabic(Modern) = 11 Roman = XI Here are the first 20 Roman Numerals 1 = I 2 = II 3 = III 4 = IV ( or IIII on classic dials of clocks). 5 = V 6 = VI 7 = VII 8 = VIII 9 = IX 10 = X 11 = XI 12 = XII 13 = XIII 14 = XIV 15 = XV 16 = XVI 17 = XVII 18 = XVIII 19 = XIX 20 = XX NB The first ;12; numbers you will find on analogue clocks with a classic dial.
12 in roman numerals is XII (10+1+1) 1938 in roman numerals is MCMXXXVIII (1000-100+1000+10+10+10+5+1+1+1_
MCMLXXIII = 1000 + (1000 - 100) + 50 + 10 + 10 + 1 + 1 + 1 = 1973.

212 in Roman numerals is CCXII (100+100+10+1+1 = 212)
It is already in Roman numerals as IX which means 10-1 = 9
XI in roman numerals, X = 10, I + 1, 10 + 1, eleven
21 in Roman numerals is XXI (10 + 10 + 1)
CXXI. In Roman Numerals, C equals 100 and X equals 10 and I equals 1. Therefore 121 would be CXXI or 100+10+10+1.
