The largest number to be denoted by a single letter was 1,000 (M). So I suppose a billion would be M repeated a million times!
1 billion in roman numerals is 'm' with two horizontal lines above it: = m
The number 1 billion can be written as the Roman numeral [M] with a horizontal bar above it (which I can't write with my keyboard). Do that four times for four billion, then add VI which is six.
The Roman numeral representation for 1 is 'I'.
1 in roman numerals is written as I.
1.5 = IS in Roman numerals because 1= I and 0.5 = S
1 billion in roman numerals is 'm' with two horizontal lines above it: = m
The number 1 billion can be written as the Roman numeral [M] with a horizontal bar above it (which I can't write with my keyboard). Do that four times for four billion, then add VI which is six.

1.5 = IS in Roman numerals because 1= I and 0.5 = S
In todays notation of Roman numerals: VIII-I-MCMXLVII
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.
4 in Roman numerals can be IIII (4) or IV (5-1)
I/i/mmxi
They are: I and LX respectively
A billion = ((((M)))) as a Roman numeral because it means 10*10*10*1000*1000 which equals 1,000,000,000 There is evidence that the Romans used brackets to indicate multiplication of numerals. For instance The Columna Rostrata which was erected to commemorate their victory over the Carthaginians the numerals of (((I))) which are carved into the monument represents: 10*10*1,000*1 = 100,000
In the same order as asked, "MCMLXXVII/I/I" The "/" is just to separate, and is not to deal with the roman numerals in any way.
