How can I set up fractions on my TI-89 calculator?

[phillipb115]

Ok, so I have a TI-89 Titanium Edition calculator. I want to know how to setup fractions on it. Like I want to be able to do it like on a regular scientific calculator where you somethign like 2 Ab/c3 and then that would give you 2 over 3 (2/3). Is it possible to set up a fraction in the calcualtor like that? I know it wouldn't be the same button and stuff, but how woudl I do it? Thanks!

A fraction can be set up by simply formatting it as a division term. If you want to add, say, 3/7 and 8/13, just type 3 (divided by) 7 (plus) 8 (divided by) 13. The solution will appear as 95/91, the exact solution, or you can have the approximate solution by pressing the diamond key before entering the expression.

Yes, it is possible to set up fractions on your TI-89 calculator. Here's how you can do it:

1. Press the "Mode" button on your calculator and scroll down to "Exact/Approx" and press "Enter".

2. Scroll down to "Exact" and press "Enter" again.

3. Press the "Apps" button and scroll down to "Symbolic" and press "Enter".

4. Scroll down to "Fraction" and press "Enter".

5. Now, when you enter a fraction like 2 Ab/c3, the calculator will automatically convert it to 2/3.

You can also use the fraction button (located above the "7" button) to enter fractions directly. For example, to enter 2/3, you would press "2" followed by the fraction button and then "3".

I hope this helps! Let me know if you have any further questions.
