Just enter it using the divide key not the fraction key. If you enter the fraction using the fraction key press the SD button. If you do not want to use fractions ( a pity) set the IO mode to LineIO instead of MathIO. Press SHIFT MODE (Setup) to do that.

SOURCE: When I divide answers are always given in Fractions. Can I change it to come out in decimals?

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

How do I convert decimals to fractions on the TI Math Explorer (No numbers associated with it - i.e. TI - 15)?


The way it works is as follow. If a result is displayed as a fraction you can convert it to its decimal representation. If you do nothing after the conversion, you can revert the decimal representation to the fraction.

F-D key in Polynomial


The F-D key converts a displayed result from fraction to decimal and vice-versa.
If in the polynomial expression a numerical coefficient is a fraction just enter it as a fraction, possibly enclosed in parentheses. If it is a decimal number just enter it as a decimal number. Converting it to a fraction is not going to generate any more precision in the result. You lose precision when you go from fraction to decimal, but you do not make a number more precise by converting it from a decimal representation to a fraction.

Conversion of decimals to fractions 0.1666666666666666666666666 = 1/6


You can always convert a fraction to a decimal. The reverse may not always be possible. Look at the example on the screen capture.

You may be lucky and recover a fraction you have just converted into decimal format, but you cannot just write 0.333333333333 and expect the calculator to convert it to 1/3: The true fraction 1/3 has an infinite number of 3's after the decimal mark.

How do you change decimals to fractions on a casio


If you enter an improper fraction or a mixed fraction with the the [a b/c] key it will be displayed as a fraction. This result being displayed you can press the [F-D] key to convert the fraction to decimal. If you do nothing else and you press the [F-D] key again, the original fraction will be restored.

However, it seems that you cannot enter an arbitrary decimal number and convert it to a fraction. The [F-D] key seems to work one way : from a fraction to a decimal number. You will only recover a fraction if the original number was a fraction.

HOW TO INTER FRACTION ON A TI-83


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
