How To Add Fractions On A Ti 84 Plus

At that place's no fraction key on the TI-84 Plus calculator, per se, but many fraction tools are congenital into this calculator. For starters, isn't a fraction just partitioning in disguise? Then, pressing / betwixt two numbers creates a fraction.

Setting the way

Practise you prefer fractions or decimals? Would y'all rather work with an improper fraction or a mixed number? There'due south no correct answer to these questions, but what would make you (or your instructor) happy? Changing the mode of your calculator forces the calculated answers into a class of your liking. Exist careful; this is a big decision on your part!

Setting the style non only affects calculations on the Abode screen, just also the way lists and sequences are displayed.

To change the form of your calculated answers, printing [MODE]. Utilise the pointer keys to coil to the 11th line, ANSWERS. Here, there are three choices that touch how calculated answers are displayed:

• Motorcar: Choosing AUTO displays the answers in a similar format to the way the expressions are entered. If the expression contains a decimal, and then you should expect the answer to exist in decimal form. If the expression is entered in fraction form, then you should expect the answer to exist expressed in fraction form. See the first screen.

• DEC: The Dec mode forces the answers to be displayed as decimals. See the second screen.

• FRAC — APPROX: When possible, the FRAC — APPROX mode displays answers as fractions. See the 3rd screen.

  

In that location'south one more than style determination you need to brand. What blazon of fraction do y'all prefer: improper fractions or mixed numbers? Press [Style] and modify the FRACTION TYPE to one of these two choices:

• n/d: Fractions are displayed in simplified fraction form.

  The numerator of a fraction must contain less than 7 digits and the denominator of a fraction must not exceed 9999.

• United nations/d: When possible, fractions are displayed equally a mixed number.

  To avoid errors and potential bug, enter U, n, and d as integers with a maximum of iii digits.

Converting fractions and decimals

There'due south an like shooting fish in a barrel way to convert a decimal to a fraction, regardless of the style setting. You can access the Frac and Dec functions in the first two options in the Math menu. The Frac function displays an respond as a fraction.

Type the expression and press [MATH][ENTER][ENTER] to brandish the expression as a fraction. Printing [MATH][ENTER][ENTER], and your answer is converted to a fraction. Meet the beginning screen. If your calculator can't catechumen an expression to a fraction, information technology lets y'all know past redisplaying the decimal.

How do you catechumen an infinite repeating decimal into a fraction? Just type at to the lowest degree ten digits of the repeating decimal and press [MATH][ENTER][ENTER]. Run into the second screen.

The Dec part converts a fraction to a decimal. Enter the fraction and press [MATH][two][ENTER]. Of course, if yous're non thinking alee and your answer is in fraction form, just press [MATH][2][ENTER] to display your answer equally a decimal. An example is shown in the tertiary screen.

Accessing shortcut menus

Did you know that there are four hidden shortcut menus on your calculator? The four menus are: FRAC (Fraction menu), FUNC (Function menu), MTRX (Matrix menu), and YVAR (Y-variables menu). To access the hidden FRAC carte du jour, press [ALPHA][Y=]. Meet the get-go screen. Notice that later pressing [ALPHA], the keys at the top of your keypad go soft keys that activate on-screen menus.

The MTRX menu can only exist accessed by pressing [Blastoff][ZOOM] to access the MTRX shortcut menu. However, the residual of the shortcut menus can besides be accessed by standard menus. For example, the FRAC bill of fare tin can also be accessed in two places in the MATH menu. Printing

(at the bottom of the NUM menu) to find the FRAC menu in a standard menu. Run across the 2d and third screens.

Inbound fractions and mixed numbers

Press [Blastoff][Y=] to access the FRAC card. The starting time two options in the FRAC menu are piece of cake-to-apply fraction templates:

• due north/d: Enter fractions in the fraction template.

• United nations/d: Enter fractions in the mixed number template. See the first screen.

The side by side 2 options are used for conversion:

• Converts a mixed number to an improper fraction, or an improper fraction to a mixed number. Run across the second screen.

• Converts a fraction to a decimal, or vice versa. See the third screen.

  

Inbound complex numbers in fractions

The n/d fraction template has its limitations. Complex numbers may not exist used in the due north/d fraction template. To enter the complex number, i , press [ALPHA][.]. Inbound a complex number in the n/d fraction template produces an fault message as seen in the offset screen.

Don't worry! You can enter complex numbers into fractions the sometime-fashioned way, using parentheses and the division key. Your calculator automatically simplifies fractions that incorporate a circuitous number in the denominator. See the 2d screen.

Entering circuitous fractions

Circuitous fractions are fractions that comprise one or more than fractions in the numerator or denominator. In other words, complex fractions accept fractions inside of fractions. No problem. Complex fractions can hands be entered in your figurer past using the n/d fraction template multiple times in the same fraction.

Press [ALPHA][Y=] to access the n/d fraction template.
