The key marked [a b/c], the one below the [X,Theta,T] and [7], allows you to enter fractions either as mixed numbers or improper fractions.

To enter the mixed number 3 4/7 you key in **3 [a b/c] 4 [a b/c] 7 [EXE]**

To convert this to an improper fraction press [SHIFT] [F--D].

Pressing the [F--D] key toggles between fraction and decimal representation.

You have two Input/Output modes MathIO, LineIO. The latter is the old way of presenting fractions with the u or wedge as a separator. MathI0 displays fractions as you would see them in textbook.

Set the input/output display to MathIO.

To do so, reset your calculator or Press [SHIFT][Mode](Setup) and select 1:MathIO.

To input fraction on a TI83PLUS you enter a numerator, press the division key thaen the denominator. But before pressing the ENTER to execute the command, press the MATH button. In the new screen that displays, select the option 1:>Frac. At this point your comiand line has [numerator] [/] [denominator] [>Frac]. Press ENTER to valodate. The fraction entered will be kept in fraction format but reduced to its simplest terms.

If you have a TI84Plus, then the newer OS (2.43MP ) handle fractions much better than OS 1.19 of the TI83Plus.

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).**

To enter the fraction two-thirds (2/3), first enter the number two. Then press the key that is the letter n with a bar underneath it. This will designate the 2 as the numerator of the fraction. Then, enter the number 3 followed by the key that is the letter d with a bar over it. That designates the 3 as the denominator of the fraction.

Any fraction can be inputted in the same manner. First the numerator followed by the n with a bar under it, then the denominator followed by the d with the bar over it. Once your fraction is inputted, continue with your computations as normal.

The following examples will demonstrate how to
convert decimals into fractions using the TI-30Xa and TI-30Xa Solar.
Please be aware that TI-30Xa Solar School Edition calculators do not
have this functionality.

**Example**: Convert .25 to 1/4

- Input .25, press [2nd][<--] (says F<>D above it).

**** F<>D means fraction to decimal, decimal to fraction. **

**Example**: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

**Example**: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

- Input .25, press [2nd][<--] (says F<>D above it).

- Input 1.38, press [2nd][<--].

- Input 9.75, press [2nd]{<--].

What is the question? Do you want fractions or not?

- If you want to perform exact calculations (that is with fractions and radicals) you should set the calculator Input-output mode to MathIO. Even with this mode set as default you can still convert the final result to a decimal number. This can be done 2 ways.

- Result is already displayed in fraction/radical format: Press the [S-D] key to toggle between the two formats.
- Result has not been calculated yed (expression still in command line), then press [SHIFT][=] to ensure it is displayed in decimal format.

- If you do not want fractions nor radicals (roots) just set the default Input-Output to LineIO

- Press [SHIFT][MODE] to open setUp and select [1:MathIO] to select natural display with fractions/radicals.
- Press [SHIF¨][MODE] and select [2:LineIO]
