TI-83 Plus calculator--fractions

There is no "fraction" button on the TI-83 plus. You will have to press the divide key (2 buttons below the CLEAR key) and then use the parentheses (immediately to the left of the divide key) to tell the calculator the correct order of operations. For example, "1/3x+9" means ".333333x+9", but "1/(3x)+9" means the "x" goes on the bottom of the fraction.

The TI-83 doesn't really work with fractions. You can enter a fraction as a quotient. For example, one-third can be entered as (1/3) by pressing ( 1 / 3 ). However, the calculator works with numbers in decimal format. You can convert a result to a fraction by using the >Frac command, available by pressing MATH 1.

The division sign acts like a fraction on the ti-83; to multiply two fractions you may want to wrap them both in parenthesis to get the order of operations correct.
Vote early and often

put the fractions inside brackets
(1/2) x (44/55)

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.)

Hello,
There is no key per se but a command accessible as follows
[MATH][1:->Frac] the fractions given are always reduced/

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

0.25 [MATH][1:->Frac] [ENTER] gives 1/4
Hope it helps

Just put in (5/8) and that will tell the calculator to that first then when done with the problem you press {math} then press {Frac} and it will give your answer back in a fraction

(-3/4)-(-2/5)

You MUST put parenthesis around fractions in a TI-83. If you have a fraction with multiple parts in the numerator or denominator, you MUST put parenthesis around either the numerator or denominator (depending on which one has multiple parts).

E.G.:
X*Y-L/N
Should be Typed
((X*Y-L)/N)

Make Sense?

A fraction is just division of the numerator by the denominator.  So all you have to do is enter the division symbol in place of the fraction bar.  If you are trying to enter a mixed fraction: for example 3 3/5 enter: (3+3/5) were the / is the division button or your calculator.

in order to evter a fraction you would need to do (4/9)+(5/9) and to get teh answer as a fraction you would go to test and select >frac
