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 do I change a percentage to a fraction

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

Hi i have a TI-34-II and i need someone to tel me how to change a fraction into a percent and how to chance a fraction into a decimal. please help!!


One can express percentages as fractions. Say you have 60% and you want to change this into a fraction. you can also express this as 60/100 because all percentages are are parts of 100. So to change a fraction into a percent you would just convert the fraction into a decimal by dividing (3/4 = .75). Then to get the percentage you just multiply the decimal by 100 to get the percent. (75x100=75%

How do you figure out a percent out of, or derived, from an improper fraction?


Express the improper fraction as a decimal. Then multiply the whole by 100%.
Example 2 and 1 over 3 becomes 2.3333. In percent that gives 233.333%

I have the sharp model EL-W535. When I divide not whole numbers for example 9 divided by 5 they come up as fractions instead of decimals and i can change it from fractions to decimals but it's very time...


To change from fraction to decimal, all it takes is a keypress. (change key)
.Not all decimal results (approximations) will be converted to fractions.
Anyway, if you want to set the calculator to display decimal results only,
Press SETUP
Press 2:EDITOR
Select 1:LINE.

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.
