# How To Do A Fraction On A Ti-84 Plus

Your TI-84 Plus can perform a wide range of functions, from graphing and calculating logarithms to crunching matrices and doing calculus. However, one of the challenges users face is entering fractions or mixed numbers due to the absence of a dedicated key for these functions. Despite this, there are several ways to input fractions and mixed numbers on your TI-84 Plus calculator.

## Entering Fractions on Your TI-84 Plus

To enter a fraction on your TI-84 Plus, you can utilize the FRAC menu. Start by pressing the Alpha key followed by the Y= key to access the shortcut menus. Once the FRAC menu is displayed, select the n/d function to bring up the template for creating a fraction. Input the numerator and denominator of your fraction using the navigation keys.

## Entering Mixed Numbers

If you need to enter a mixed number, you can also use the FRAC menu. By pressing ALPHA and then Y=, you can access the FRAC menu and select the Un/d option to input the whole number, numerator, and denominator of the mixed number using the template.

## Other Options in the FRAC Menu

Aside from entering fractions and mixed numbers, the FRAC menu offers additional functions. You can convert improper fractions into mixed numbers and vice versa by selecting the appropriate option. Furthermore, the menu allows you to convert fractions to decimals and back again.

## Setting the Results Mode

Your TI-84 Plus calculator provides mode settings that allow you to customize how your answers are displayed. By pressing the MODE button, you can select the desired format for your results, such as improper fractions, mixed numbers, decimals, or automatic display based on the input format.

## Converting Fractions and Decimals

If you need to convert a decimal to a fraction or vice versa, the calculator offers the Frac and Dec functions in the Math menu. These functions enable you to easily switch between decimal and fractional representations of numbers.

## Accessing Shortcut Menus

There are four hidden shortcut menus on the TI-84 Plus calculator, including the FRAC menu. These menus can be accessed by pressing specific key combinations, allowing you to utilize various functions and templates conveniently.

## Entering Complex Numbers in Fractions

While the n/d fraction template has its limitations when it comes to complex numbers, you can still input complex numbers into fractions using parentheses and the division key. The calculator automatically simplifies fractions containing complex numbers in the denominator.

## Entering Complex Fractions

Complex fractions, which contain fractions within the numerator or denominator, can be entered using the n/d fraction template multiple times within the same fraction. This allows you to work with complex mathematical expressions effectively.
