How do you enter a fraction - Texas Instruments TI-83 Plus Calculator

Use the key marked [a b/c]

• To enter a mixed fraction, enter integral part, press [a b/c], enter the numerator pf fraction part, press [a b/c], then enter the denominator of the fraction and press =.
  
• To enter a fraction or an improper fraction, enter numerator, press [a b/c], then the denominator and =
• If the displayed result is a mixed number , use [2nd][a b/c] to convert it in a fraction (improper fraction).
  

Enter the whole number ,then hit ab/c on your calculator enter the upper number of the fraction then hit again ab/c then enter the lower number of the fraction.That way yuo can enter a mixed fraction.Hope this helps.

To Enter a basic fraction just enter the first number, then a division sign, then the second number. So two thirds would look like "2/3" (Without quotes). For more complicated fractions you may need to put parentheses for the left and/or right of the division sign like in the fraction (5+2^4)/(2-8). To get the calculator to show it as a fraction you would enter the fraction, then press (Math) then (1:Frac). So the input on your screen should look something like this "2/3>>Frac" (Without Quotes, and >> being a filled triangle pointing at the word Frac). From your post it sounds like you were putting the fraction last when it should have gone first.

First put the calculator in degree mode.
To convert from fraction to a decimal number first enter your fraction or, mixed number. I'll convert a mixed number to a fraction first since, I don't have a key for the symbol that shows that a number is a fraction on my keyboard. Example: [3][A b/c][1][A b/c][2][A b/cd/e][ENTER]
3/2 should be entered at the home screen. While at the Home screen enter, [2nd][FD][ENTER]
1.5 should now be displayed at the Home screen.
As you can see it is really just using the [A b/c] key to enter in your fraction and, [FD] key to do the converting. The [A_b/cd/e] key isn't necessary because, mixed numbers will convert to decimal numbers just like fractions do. I just don't have the key to show a fraction symbol that the calculator uses. So to show that symbol, I used the / symbol with the fraction number.

A fraction is just a particular number.

1. Enter numerator of first fraction
2. Press the division sign
3. Enter the denominator of first fraction
4. Press the multiplication key
5. Enter second numerator
6. Press the division key
7. Enter the denominator of second fraction
8. If you want a decimal result press [ENTER]
9. However, if you want a fraction press [MATH][1:

A fraction is basically a division of two integer numbers. To enter a fraction you type the numerator, press the division key, enter the denominator and press [ENTER]. For a mixed number (integer + fraction) enter the Integral part, press [+] and then enter the fraction part as described above.

However what you really want to know is how to enter a fraction and KEEP it in a fraction format.
To do that, you enter the fraction as described above, then you press the [MATH] key and select [1:>Frac] then [ENTER}.
The fraction will keep its nature but what will be displayed is the irreducible equivalent.

Does what I said sound too difficult? Well, Cheer up. TI has issued a major upgrade to the OS of the TI84PLUS/TI84PLUS SE. Download the OS version 2.53 MP and install it on your calculator. The easiest way to do so is to open TIConnect on your computer, connect the calculator to the computer and click the UPDATES button in the TI Connect main window.

1. Enter a numerator, the division sign /, then the denominator.
2. Instead of pressing the [ENTER] key, press [MATH] and [1:|=>Frac]
3. The command line displays the fraction you entered, followed by the [|=>Frac] command.
4. Press [ENTER] to display a reduced (equivalent) fraction.
5. 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

1. Enter a numerator
2. Press [/] for division
   
3. Enter the denomoinator
4. Press [MATH]
5. Press [1:|=>Frac]
6. Press [ENTER]
   

Keep in mind that the fraction that will be displayed will be a fraction reduced to its simplest form.

To convert a fraction into a decimal number Press [Math][2:|=>Dec].

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

For instance, 3/4 = three fourths.

Hello,
Once you enter a fraction the calculator calculates it and displays a decimal result.So basically you cannot do fraction manipulations. However you can convert a decimal result into a fraction. To do the conversion, you enter the decimal number then you Press [MATH] and [1]. ( -->Frac) The number will be converted.
Similarly you can enter a fraction to a decimal number (-->Dec)
[MATH] [2:] [ENTER]. But I see no point in doing that, because any fraction entered is displayed as a decimal number.

Hope it helps
