I CANT GET MYCALCULATOR TO DO FRACTIONS CAN YOU HOPE ME


To configure the calculator to do fractions, set the Input/Output mode to MathIO.
Press [SHIFT][MODE] to open (SetUp) then select [1:MathIO].
After you set it to MathIO, pressing the fraction key will display a fraction template where you can enter numerator and denominator as you would by hand (horizontal fraction bar). Also, the calculator will display results as fractions and radicals whenever possible.
To perform arithmetic operations on fractions use the regular operation keys (x, +, -, /). The calculator will perform the operations and display the results as fractions (whenever possible).

I have an fx-300es scientific calculator. It doesn't have an ab/c button. Does another button function like an ab/c button?


The calculator has a key marked with two squares on top of one another and with a fraction bar between them. The key is to the left, below the ABS key..
The shifted function of that key is the mixed fraction [a b/c]. I am not convinced you need a specific key to enter a mixed fraction: you can just type in the integer part (whole part) then + then use the fraction key (the one with the two squares.)

Is there a button for adding fractions?


There is only one button to effect addition and that is the one marked with a plus [+] sign. It performs addition for all numbers, be they decimals , fractions. It can also be used to add lists or matrices.
To force an entered fraction to remain a fraction (allbeit reduced to its simplest form) press [MATH][1:>Frac] before pressing the ENTER key.
That is the hard way to do it.
However, if you are willing to upgrade the calculator's OS to version 2.53 M(ath)P(rint) you will be able to handle fractions much more easily. You will also be able to calculate logarithms in any base.

The OS upgrade is available at education.ti.com. Here is the link to it.
Use the TIConnect software to transfer it (batteries much be good). You can also transfer it from a calculator that has it.
It is not to be used with the TI83PLUS.

I can't find this button on my calculator / this


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.

The fraction symbol is ab/c
All scientific/graphics calculators have a fraction key. Going by the picture I would assume that calculator would have it

Yeah, there isn't a fraction button on an 84. You have to enter it manually as 4/9 or if simplifying a decimal, use the Ans>Frac under the MATH menu

What keys due i use to calculate a fraction, where is the fraction key


To do fractions, just use the normal divide button.
To see the exact answer, hit MODE and scroll down to Exact/Approx and change to EXACT. In this mode, it will give the fraction always unless you press the special (green button with diamond) before pressing ENTER and it will give the approximate decimal value.
