I know how to do some crazy things on the 89, but this one simple thing is driving me crazy. How do you convert a decimal into a fraction
If you type 2,/,3,enter, the ti-89 returns "2/3". If you hit the yellow key with the diamond on it before the enter key, you get .666667 (the decimal approximation). Is that what you are looking for?How do you convert a decimal into a fraction
No, i want to know how to turn .666667 into 2/3
To my knowledge, the TI-89 does not have the "convert to fraction" utility. You'll just have to learn the basic fractions yourself, or do the conversion process yourself. Sorry.

I believe the 89 is programmed to give exact values only. It will approximate exact values if you want it to, but it will not "lie" and do the opposite.
For example, it will tell you pi/1.0=3.14159, but it will not say that 3.14159=pi.
go to mode press f2 go down to exact/approx and turn it to approximateor exact
Lucky for you, I'm here to help, and the rest of the replies here are worthless piles of information.
To turn a decimal into a fraction on a TI 89: Type in "exact(_______,01)", without the quotations. The blank space is where your decimal goes, followed by a comma and the numbers zero one comma.
Example: to find the fraction of 1.33333, this is how it will look from your home screen:
exact(1.33333,01)
The result will be: 4/3
The "01" specifies the tolerance of the search.
....Your welcome.
Wow, rudedog, thanks for that bit of info . I didn't know that. I just tried it on my 92 and it worked as well.
Actually, I think all you have to do is to change every number to fraction.
