Question about Texas Instruments TI-84 Plus Calculator

Ad

- Enter a numerator, the division sign /, then the denominator.
- Instead of pressing the [ENTER] key, press [MATH] and [1:|=>Frac]
- The command line displays the fraction you entered, followed by the [|=>Frac] command.
- Press [ENTER] to display a reduced (equivalent) fraction.
- If you keep using the sequence [1:|=>Frac][ENTER] with all your fractions you can keep getting fraction results.

The OS of the calculators Ti84PLUS and TI84Plus SE has been upgraded recently to the 2.53MP (math Print) version, which provides some significant improvement to the handling of Fractions, Logarithms, etc. Unfortunately for you, the upgrade is not compatible with the TI83PLUS

The Frac command only works if the number can be expressed as a fraction with no more than three digits in the denominator. Since the square root of 5/9 is an irrational number, it cannot be expressed as a fraction at all. The calculator is telling you that the value cannot be adequately approximated as a fraction with three or fewer digits in the denominator.

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.

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

just type it in, e.g. 1/2 or 3/5.
if you want to have answers display as fractions, press [MATH] ENTER.

(-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?
