Where is the fraction key on this calculator?


There isn't one. You can convert some values to fractional form by using the >Frac command on the Math menu available by pressing the MATH key. You can enter a fraction as a quotient, but the calculator deals with the number internally by converting it to decimal form.

For example, to see one-half plus one-third, press
( 1 / 2 ) + ( 1 / 3 ) MATH 1 ENTER

How do you enter a fraction


A fraction is just a division of two integers. Enter numerator, then press the division key and then the denominator.

If you press ENTER at this time your fraction will be calculated and displayed as a decimal number.
To keep it in fraction form you must press [MATH][1:>Frac]. The result will be a fraction but reduced to its simplest terms (an irreducible fraction).

27 [/] 48 [MATH][1:>Frac][ENTER] gives 9/16

I have to learn how to operate a texas instrument TI-83 to do math (fraction)


This calculator, although very sophisticated, is rather unfit for heavy fraction calculations. There is no dedicated fraction key, but you can use the [MATH] menu to access a ToFraction command: symbolized by a fat arrow and Frac.
I am enclosing a few screen captures to help you figure out how to use your calculator to manipulate fractions. To get the first screen you press the [MATH] key (below the [ALPHA] key. The ToFraction command is the first one in the list. The second item allows you to convert a fraction to a decimal number.

In the following screen I show you how to enter a fraction (division key) and keep it in fraction form, albeit reduced. Fractions are reduced to their simplest terms

In the last screen, I show you how to convert a fraction to a decimal number by making use of the ToDecimal command (last command line on the left, result is one line down and to the right.)

Can't find fraction button.


Hello,
There is no fraction button, but if you divide two integers (whole numbers) and want to keep the result as a fraction press [MATH][1:|=>Frac] [ENTER]. If the fraction can be reduced to its simplest form that is the result you will have.
27/48 [MATH][1:|=>Frac][ENTER] displays 9/16
Hope it helps.

I don't know how to use fractions


Enter any fraction as a division problem and your TI 83 will evaluate it as a fraction.

For instance, 3/4 = three fourths.

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.

How to us a fraction on the ti-83 calculator? I have home work due on this tues. and i dont know how to put a fraction in on this calculator .


Hello,

Ther e is no dedicated key to do that but ther is a command ToFrac noted as ->Frac. To access it use [MATH[1:->Frac].

Two ways of using the command.
1. You want to reduce a fraction to its simplest expression
27/48 [MATH][1:->Frac] [ENTER] gives the reduced fraction 9/16

2 You do not want your results converted to decimal numbers

(27/48) [x] (5/7) [MATH][1:->Frac][ENTER] multiplies the two fractions and gives a fraction as a result. 45/112

3. Your result is in decimal form and you want to cast it into a fraction. The conversion will be exact only for certain numbers. Results kept in fraction forms are more accurate than those represented as decimals.
Hope it answers your question.

Where is the fraction button on the ti 83 plus cac. look like


Hello,
There is no fraction button. Any division of two integers you do is represented as a decimal number. If you want your fraction to remain a fraction you enter it as follows
7[ / ] 19 [ MATH][1:ToFrac] [=] displays 7/19
If you want to convert a decimal number into a proper fraction press [MATH][1:ToFrac] .
Exemple 7/19 [ENTER] gives .36842105. If without doing anything else, you press [MATH][1:ToFrac] you recover 7/19.
There are limitations related to the number of decimal digits in the floating point number.
.3684 [MATH][1:ToFrac][=] gives 921/2500 but
.36842 [MATH][1:ToFrac][=] gives .36842 : it is not converted to fraction.

Hope it helps
