they are equal, and it has nothing to do with baldys explaintion

we are going to do a simple proof. we are going to change a repeating decimal to a fraction. anyone taking college level math should know how to do this.

let x = .999~  
mult both sides of the equation by 10  
10x = 9.999~  
subtract the original equation, leaving you with  
9x = 9 (the repeating part is removed)  
divide by 9  
x = 1

thats the proof.

you can argue all you want, but i called my old man to confirm… he’s a math teacher. as a matter of fact, i think someone on the forum is/was in one of his classes.

scroll down a hair, and you will see that my math is right
