What is the roman number lxix?

Answer 1

LXIX is the Roman numeral for the Arabic number 69.

To understand Roman numerals, one first has to understand what the numerals represent:

I=1

V=5

X=10

L=50

C=100

D=500

M=1,000

When the larger Roman numeral is in front followed by the smaller, you add the two, as in VI (5+1=6).

When the smaller Roman numeral is in front, you subtract it from the one following it, as in IV (1 from 5=4).

Therefore, LXIX is broken down as LX (50+10, or 60) + IX (1 from 10, or 9) = 69.

That's why you'll sometimes see strings of Roman numerals referring to copyright dates in movies as MCMXCVIIII. Broken down, M=1,000 + CM (100 from 1,000, or 900) + XC (10 from 100, or 90) + VIIII (5+4, or 9), or "1999."
