There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

There isn't one. If you want to convert a value from decimal to fraction, use the >Frac function (press MATH 1). If you want to enter a fraction, simply enter the numerator, divide, then the denominator.

For example, to calculate 1/4 + 1/3, press

( 1 / 4 ) + ( 1 / 3 ) MATH 1 ENTER

and you'll see 7/12.

There is no key nor command to calculate percentages. But that is easy to correct.

Percentages

To go from a decimal result to a percentage, move the decimal mark 2 places to the right. If you have no decimal mark as with integers, put a decimal mark at the end of the number pad it with zeros, then move the decimal mark 2 places to the right.

Ex: 0.73 in % gives 73.0%

Ex: 2.33 in % gives 233.00 %

Ex: 5 in % 5=5.00 becomes 500%

Fractions

The calculators has a command to convert a decimal number to a fraction. The command is called >Frac or To frac. You find it under the MATH key.

Enter a number (decimal or fraction)

Press [MATH][1:>Frac]

Command echoes on main screen after the number you entered.

Press [ENTER] the result is displayed as a fraction.

The TI 84PLUS and TI84PLUS Silver edition OS has seen a major upgrade to version 2.53 M(ath)P(rint). If you play a lot with fractions this new OS will allow you to do a lot more than what is described above.

Here is the link to download the new OS version. It cannot be transferred to a TI83PLUS or TI83PLUS SE.

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

Enter the fraction for example: enter 8/12.

The answer will be .666666

Then click Math (which is located under the Alpha button).

Click the ->Frac button (the first one).

It should come up as Ans->Frac.

Click Enter.

It should now read 2/3 which is 8/12 reduced.

Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition

The answer will be .666666

Then click Math (which is located under the Alpha button).
