# 1 = .999

## Recommended Posts

1/3 = .333...(1/3)(3) = .333...(3)1 = .999

you forgot these ...so, .333...(3) = .999... (approx= 1.0)close enough for measuring plywood.

This stuff doesn't make any sense. What are you trying to prove? I mean, 1/3*3=1 ... end of story, finito. If you had proved 1=2 then maybe you would have been appreciated for your witticism (is that spelled right?), but 0.999999.... = 1 ?!!

When I was in school to multiply a fraction you multiplied the numerator the top part by the number (in this case 3) so you ended up with 3/3 or reduced it is one. So 1/3 * 4= 1 1/3 I like this too then if it is a pizza I east the 1/3 myself and tell everbody i have a pizza cut into three pieces one for everone (except I stashed my other third in my beedroom for later).

Well, 1 = 2 according to this proof, which is of course false. But the trick is to figure out which step is incorrect. We went over that in my math class last semesters. We had fun trying to figure out where the proof went wrong.

And no. I wasn't the person in the class who found it first. *grins*

As soon as you round it's not equal, its approximate. If you can play with approximations as euqalities you can 'prove' alot of math formulas that are, in fact, complete and utter crap.

Hardly related but: Can anyone here think of a word (English word) that when spelled correctly spells out 4 english words (without spaces of course)? Mail me if you think you have a/the answer.

1/3 != 0.333...=> 1/3*3 != 0.999...0.999... = 8.(9)/9Duh...

If you're interested in flawed mathematical proofs, then there's a couple here:
