what is the Roman Numeral for 0.5?

Question

I've been asking everyone i know and no one knows

Answer 1

The Romans did not use decimals; their counting system was based upon the number five.

I am sure they were able to express simple fractions, using the Latin equivalent of one half, one quarter, etc.

Answer 2

The Romans didn't have a standard way of writing fractions (or decimals.)
Usually, they just wrote out the appropriate word, such as "tres septimae"
for three-sevenths.

When they needed to do serious calculations with fractions, the Romans
used the uncia, a unit that meant 1/12 of anything. There were names and
symbols for different multiples of the uncia. For example, six unciae,
or 6/12, made up the semis. The semis meant one-half, and its symbol
was an S cut in half (this looks a lot like a backward 2.) Unfortunately,
uncia symbols didn't follow any real system, and they were never entirely
standardized.

Answer 3

S is the Roman numeral for 0.5

The Romans did most of their practical calculations with fractions by using the uncia. The uncia started out as 1/12 of the as, a unit of weight (the word uncia is related to our word "ounce"), but it soon came to mean 1/12 of anything. You can add up twelfths to make halves, thirds, or quarters, so the uncia was fairly versatile. When they wanted smaller fractions, the Romans usually cut the uncia into smaller parts. The system is very similar to measuring length in inches and fractions of the inch: you might not measure an object's length exactly, but you can still come very close.

There were Roman and medieval symbols for multiples of the uncia. The semis, which was six unciae, or one-half, was often represented by this symbol: S. However, uncia symbols were never standardized, and not everybody used them. Some late medieval writers even substituted the modern fraction bar.

Answer 4

It is an "S" or as it is called a "semis" (see http://en.wikipedia.org/wiki/Roman_numbers#Fractions ) This symbol is used to represent 6/12 or 1/2 is based on their coinage system.

Good Luck!!!

Answer 5

I am pretty sure there is no numeral number zero So 05/05/08 would be V/V/I

Answer 6

i don't think they have decimals... I think they just say half 'I' in Roman....

Answer 7

S
