What is. 16 repeating as a simplified fraction?

I'm assuming this is 0.1666666 ...

Which in that case is 1/6.

(Just from memory)

To do 0.161616161616 ...

First, assign 0.161616 ... a variable, say it's x.

Now say 100x, what is it.

16.1616161616 ...

Now subtract x from 100x.

16.161616161616 ... - 0.16161616 ...

Or, 99x

99x = 16 in this case right now

Divide both sides by 99

x = 16/99

So it really depends what's repeating, it's either 1/6 or 16/99.
