6 is VI 1 is I 2009 is MMIX
I/VI/MMIX
III-VI-MMIX
As you asked this question on 15th September 2009, which can also be written as 15-09-2009, this date in Roman numerals would be XV.IX.MMIX
June = VI 6 = VI 2009 = MMIX VI / VI / MMIX
VI is 6 in Roman numerals.
VI = 6 V=5 I=1 VI means 5+1=6 VI equals 6 because in Roman Numerals V=5 and I=1 V(5)+I(1)=6
VI is 6
VI is the number 6 in Roman numerals. 6VI = 6
VI (5+1 = 6)
6 = VI
In today's terms 6-27-2009 expressed in Roman numerals is VI-XXVII-MMIX. However, the Romans themselves would have probably wrote out the number 2009 as MMVIIII which can be simplified to IMMX.
