I was wanting to know how I can use the graphing calculator to take a decimal and change it into an irrational fraction. Is there some sort of setup I can use...Thanks!
You don't really need to make the calculator do it, but if you want to try what I would suggest is to put the calcuator into "exact" mode, then enter your decimal, followed by "enter." It should give you back a fraction. The problem is that if you put in 0.333333 you will get back:
There's no way I know of to get around the problem of repeating decimals.
