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

If you mean to add fractions or something you would need to have (4/9)+(5/9)
If you mean to convert an answer to a fraction you would then go to test and hit the >Frac selection.

How do you use the fraction button


The fraction button is usually marked [a b/c]. Its shifted function [d/c] converts a mixed number into an improper fraction.
To enter a mixed number, say 7 3/5
Enter 7, press the [a b/c] key, enter 3, press the [a b/c] key, enter 5. Press =/EXE

Why cant anyone tell me how to do fractions on my calculator i dont have the / button


Yes, you do have the division key. It is the division key. However, if you want the fraction to remain a fraction, enter the numerator, press the division key, type in the denominator then Press [MATH] [1:>Frac] then press ENTER. The fraction that will be displayed will be the reduced form.

I need to know which button is the inverse button on my Ti-36X Pro please!


The inverse of what&? Each inverse function uses the same key (shifted) as its direct function. For the reciprocal key look for x^-1 or [1/X]

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.)

I'm trying to find the fraction button on my texas instrument ti 83 plus calculator and cannot find it


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.

How to put in a faction to solve a math problem


To enter an improper fraction you just use the division button. For a mixed fraction you use the [a b/c] key as follows:
5 3/7: Type 5 [a b/c] 3 [a b/c] 7 [=]
To convert a fraction result to an improper fraction use key sequence [2nd] [a b/c] (d/c).

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.

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.
