So I don't know what I'm doing when turning a repeating decimal into a fraction, I've done this so much before but my brain is so cooked right now so I need help. The equation for what to do would be helpful.

There really isn't a direct explanation for this, but I'll try my best. Say 0.x repeating is a decimal, and you want to convert it to a fraction. First, name that value and name 10 times that value 10n. Equation below:

 

 n = 0.xx...

10n = x.xx...

{Minus n from both sides}

 9n = x

 n = x/9

cool
