Good evening,
I am in the second year of high school this year, and I have a TI-82 Stats.fr calculator.
I am looking for how to simplify a fraction with this calculator.
Because last year I could do it using the S<=>D button on the Casio fx-92.
Thank you in advance!

    Press the "alpha" and "enter" keys to make "resol" or press the "math" key and then the "2" and "enter" keys.

      Hello, I’m in my final year and I have roughly the same problem except that my calculator gives me everything in decimals, making it difficult to provide an accurate result. I would like to know how we can convert the result into fractions because even pressing math > fraction doesn’t work... Thank you in advance!

        Hello,


        It doesn't work when the number we're trying to convert isn't a rational number.

        Example:

        • With 0.5 we get 1/2
        • But with 0.500001 it doesn't work!

        So you must have applied the function ►Frac to a number coming from a calculation that wasn't a rational number.
