To convert a single result from fraction to decimal, press Diamond followed by ENTER.

To make the calculator do everything in decimal instead of fraction, press MODE, then F2. Scroll down to "Exact/Approx", then press right-arrow. Change the setting from EXACT to one of the others.

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

How to convert percent to fraction

  1. Divide the percent by 100 to get decimal number.
  2. Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
  3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
    Example:
    f = 10 power 2 = 100
  4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
    Example:
    2.56 * 100 / 100 = 256 / 100
  5. Find the greatest common divisor (gcd) of the fraction. Example:
    gcd(256,100) = 4
  6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
    256 / 100 = (256/4) / (100/4) = 64/25
Example One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25

Casio-fx300 ES if i enter 2.5+2 it answers as a fraction of 9/2 how do i reset this to calculate correctly


There is a misconception that fraction are less correct than decimal result. Quite the contrary. Calculations with fractions and/or with radicals are exact while decimal calculations are approximate.
Anyway, you want decimals and so decimals you will have.
When a result is displayed in fraction or radical (root form), just press the [SD] key and it will give you the so desired decimal representation.
If somehow you cannot stand the sight of a fraction or a radical, just tell your calculator so.
Press [SHIFT] [MODE] to open (SetUp) screen and press [2:LineIO]

How to convert fractions to decimals


To convert fractions to decimals, and decimals to fractions use the [a b/c] key. If the total number of symbols (num, denom, fraction bar) to display a fraction exceeds 10, the fraction is automatically converted to decimal format.

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
