# Joke : Prove that 6 = 8.5

#### Shared by Zi Song Yeoh 14, Malaysia · 2 years, 4 months ago

What is $$6$$ in English? It is six. But what about six in numerals? You might say : "Of course its $$6$$!". Yes, but it is also $$8.5$$ ! If you didn't believe me, write $$8.5$$ in Roman numerals and you'll get SIX!

Thus, we get $$6 = 8.5$$!

Note : For those who are not familiar to Roman Numerals, $$S = \frac {1}{2} = 0.5, I = 1, X = 10$$, and so $$SIX = 10 - 1 - 0.5 = 8.5$$

See this for more details on fractions in Roman Numerals

For those who don't know why $$S = \frac {1}{2} = 0.5, I = 1, X = 10 \Rightarrow SIX = 8.5$$ :

Note that $$IV = 4$$, but $$V = 5, I = 1$$, so $$IV = V - I = 4$$, and so similarly $$SIX = X - I - S = 8.5$$.

Alternatively, you remove 1/2 from 6 and you get 9 ;)
