  1. If a fraction (or a radical) is already displayed press the [S<=>D] key to convert it into a decimal number.
  2. If you are entering an expression and want its result displayed as a decimal number, press the [SHIFT][=] key sequence instead of just [=].
  3. More permanent solution: If you do not want fractions nor radicals, configure the Input/Output to be LineIO. To do that, press [SHIFT][MODE] to access the (SETUP) then select the option [2:LineIO]

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

It is showing fractions instead of Decimals when i do equations like (4 divided by 9) it gives 4/9 instead of the decimal.


Calculation results will be displayed using
fractions, r, and ?. When you press CHANGE, the display will cycle
through the following display styles:
• Mixed fractions (with or without ?) ? improper fractions (with
or without ?) ? decimal numbers
• Proper fractions (with or without ?) ? decimal numbers.

Whenever i do a large sum, for example 102795/600,...


Let us first set the record straight: Your calculation is a division not an addition. Be it as it may, the result you obtain is correct the fraction is equivalent to the one you entered, the difference lie in the fact that the calculator reduces the (entered) fraction to its simplest form.
Both the numerator and the denomonator have been divided by 15.

If the result is already calculated and displayed, press the [S<=>D] key It will convert a fraction or radical to decimal. This is always possible. If the result is decimal it may be converted to a fraction or a radical (Not always possible).

If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].

More permanently. If you do n o care for fractions and radicals, set the Input/Outpout mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

When doing division only displays answer in fractions, for example 8/9 gives me 8/9 rather than the decimal equivalent


  1. Press [S<=>D] key to toggle between fractions/radicals and decimal numbers.
  2. Alternatively, press [SHIFT][=] instead of [=] to force display to be in decimal format.
  3. More permanently, press [SHIFT] [MODE] to access (SETUP) screen, then select [ 2:LineIO]

When I divide, I get a fraction. How do I get a decimal


If your calculator is configured to be in MthIO, the fraction that is displayed is always reduced to its simplest form. (The denominator is the smallest possible.)
If you are adding fractions, the result is also a fraction in its reduced form.
If you want to convert a fraction to a decimal number, press the [S<=>D] key.

To set MthIO: Press [SHIFT][MODE] (SetUp) and select [1:MthIO]
To set LineIO: Press [SHIFT][MODE](SetUp) and select [2:LineIO]
In LineIO, all results are expressed in decimal format.

When I divide the answer is in fraction form not decimal form how do i get it back


There are two options.

1) Whenever you want the answer in decimal form, place a decimal after at least one of the numbers.
For example: instead of using (1/2) use (1/2.)

2) Press the "Mode" button. Scroll down the list that appears until you find "Exact/Approx". If you set it to "Approximate", then it will always give the answer in decimal form. If you set it to "Exact", it will give the answer in fraction form.

When I try to divide numbers that would leave a remainder like 1 divided by 6 which should give me an answer like 0.16666666666 instead all it says for an answer is 1/6. it does say in the manual to input...


Hello,
To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.
Dans ce cas 1/6 is displayes ase 0.167.
Hope it helps.

Division


it took me a while to figure it out too but i found out how. Put in, for example, 3 divided by 2. You get 3/2. Then press the button right above DEL. (it says S<=>D) and it will convert the fraction to a decimal. To change the number of decimal places shown, push SHIFT then SETUP then 6 then a number from 1-9 and that is how many decimal places will be shown.

Fraction problem


Go into MODE to the second page.  In Exact/Approximate, change it to Approx instead of Auto or Exact.  This will give you decimals instead of fractions.
