You have to set how the calculator handles numbers. To do this follow these steps: 1. Press the 'MODE' button. This brings up the calculator's main settings page. 2. Scroll down until you reach a field titled 'Exact/Approx...'. This is the setting for how the calculator handles numbers, whether it will show the exact answer (which is usually in fraction format) or whether it will show an approximate number (which will be in decimal format). 3. Press the right arrow which will bring up the options for that setting. You must now choose between three ways of handling numbers: -'1:AUTO' will determine which type of answer the calculator will give based on what numbers you want it to calculate (e.g. if you want an answer in decimal format just add a decimal somewhere in your problem). -'2:EXACT' will automatically display all answers in either whole number format or in fraction format. -'3:APPROXIMATE' will automatically display all answers in decimal format. 4. After you have selected one of those options pres enter one more time to get out of the 'MODE' dialogue and return to the 'HOME' screen. Now try a problem and see what happens. Personally I like using 'AUTO' because then I don't have to keep returning to 'MODE' when I want either or. Hope this helped, I had the same problem when I first started using the TI-89.

After calculation, just press key [SD] to display it as decimal number.

If you want to see solutions as decimal numbers press [SHIFT][MODE][2].

Please rate my answer if I helped you :)

Yes, there is a feature or, setting in the mode that will stop you from converting fractions. Go to the mode screen by pressing the [MODE] key. [Down arrow] 9 times and, highlight and select the n/d by pressing the [ENTER] key. Next, [Down arrow] 1 time and, highlight and select Frac by pressing [ENTER] key. Just escape or, quit out of the mode screen and, the calculator should now be set up to convert your fractions. Just remember to go back and, change the last setting you made when you go back to dealing with decimal numbers.

The TI 83, 84 series can not set up the answers as fraction. What you have to do to get fraction answer is to go to math,1. the very first selection which is ->frac. What will change your answers into fractions

You can always convert a fraction to a decimal. The reverse may not
always be possible. Look at the example on the screen capture.

You may be lucky and recover a fraction you have just converted into decimal format, but you cannot just write 0.333333333333 and expect the calculator to convert it to 1/3: The true fraction 1/3 has an infinite number of 3's after the decimal mark.

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

When you get a fraction for he answer: shift-S<->D[a b/c<->d/c]

This way, you change it to a mixed fraction or improper fraction

You need to change a setting in the mode menu.

Change exact/approx to approximate and your answer will be given in decimal.

go to mode and scroll down to exact/approx, exact will give fractions, approximate will give decimal, change it to approximate and press enter twice to save it, that should solve it, let me know of any other questions that you may have
