The MATH menu has two options 1:>Frac, 2:>Dec.

The first entered on the command line after a fraction keeps the result in (reduced) fraction form. On a displayed result, it converts a decimal into a fraction.

The second 2:>DEC converts a fraction into a decimal number.

The latest OS (2.53MP and following) has a better handling for fractions.

A fraction is in fact a ratio of two number: a division of a numerator by a denominator. The key used for the division operation is the one above the multiplication sign and below the caret [^], and in thee rightmost column of keys.

Beware that this calculator converts any ratio of two numbers into a decimal value. To keep a fraction in a fraction form you must use the [|=>Frac] or [ToFrac] command. To convert a decimal result to a fraction, use the [|=>Dec] command.

These commands are accessible through the CATALOG or more easily by pressing [MATH] (under the ALPHA key) and selecting [1:|=>Frac], or [2:|=>Dec]

Ex: to keep 27/48 in fraction form you enter

27 [/] 48 [MATH][1:|=>Frac] [ENTER]. Result is 9/16

You will notice that the resulting fraction is reduced to its simplest form.

To convert the above result from fraction to decimal press [MATH][2:|=>Dec]

A fraction can always be approximated by a decimal value but the converse is not always possible.

Hello,

You get access the command by pressing [MATH][1: |->Frac].

If you want enter a fraction and keep it as a fraction (albeit a reduced one)

key in the number then the sequence [MATH][1: |->Frac]., then [ENTER].

Practice : 27/48 [MATH][1: |->Frac] [=] gives the reduced form 9/16.

While this fraction is still in [ANS] memory, you can press [MATH][2: |->Dec] [=] to get the decimal value 0.5625

Hope it helps.

Hello,

Yes it can do fractions although it does not have a specific key.

If you want to enter a fraction and keep it in fraction form, though reduced to its simplest expression use [MATH][1:->Frac] [ENTER]

Exemple:

27/48 [MATH][1:->Frac][ENTER] displays the reduced form 9/16.

To convert a decimal number into a fraction (with the inherent loss of precision) press [MAT][1:->Frac][ENTER]

Use [MAT][2:->Dec] to convert to decimal, but this is done by default.

Hope it helps.

Hello,

Unlike other, less sophisticated calculators, the TI83Plus /TI84Plus /TI84Plus Silver Edition do not have a simple key or a command for improper fractions. However there is a command -->Frac accessible through**[MATH] key [1:-->Frac]** that expresses a result in a proper fraction format.

Here is how you would enter you calculation

3+ 1/2 +4+1/8 [MATH][1:-->Frac][ENTER] result is 61/8

You can also ease a bit on the typing by mentally adding 3 and 4

7+ 1/2 +1/8 [MATH][1:--Frac][ENTER]

You should know about the other command that converts a fraction in decimal format.**[MATH][2:-->Dec][ENTER] **

If you enter this command just after the one handled above, your screen shows [Ans][-->Dec] on one line and the result 7.625 on the next. If you do not enter a number the calculator uses the last CALCULATED result, which is stored in the system variable [Ans]

type the decimal you want to convert then press math button scroll down to were it says frac which means fraction then press enter on frac then press enter again to solve and to change it to a decimal type the fraction and press dec instead
