Question about Texas Instruments TI-30XA Calculator

Hi,

Look for a key labeled **[a b/c] **

To use it to enter mixed numbers

1 and 3/7 ** 1[a b/c] 3 [a b/c] 7 [=]** displays **1u3u7.**

In conjunction with this key, you have the function [ d/c] accessed py pressing **[2nd]d/c]**. If you want a mixed number displayed as an improper fraction press [2nd][d/c].

To toggle between fractions and decimal numbers use the [F<=>D] key.

Hope it helps.

Thanks for using FixYa

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.

Hello,

There is no fraction button, but if you divide two integers (whole numbers) and want to keep the result as a fraction press [MATH][1:|=>Frac] [ENTER]. If the fraction can be reduced to its simplest form that is the result you will have.

27/48 [MATH][1:|=>Frac][ENTER] displays 9/16

Hope it helps.

You can convert between Standard Form (with fractions and pi) or
Decimal form by using the "S<->D" button. Use Mode 1 if you
mostly prefer fraction answers and you can use the SD button to convert
to decimal or use Mode 2 if you mostly prefer decimal answers and use
the SD button to see the fraction.

I hope this helps and good luck!

there is a A b/c button. This is the button use to enter fractions. so 4/3 would be entered as 4 |A b/c| 3

If you want to have the answers in fractions as well, then I believe you hit more a few times. And then there should be a display option, in the display option, there should be a b/c. This will show your answers in fractions. Hope it helps

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

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
