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

Sharp ELW516: Changing the default display to decimal


<span><b>Getting Decimal Answers by Disabling WriteView<img src="elw516.gif" /> on the Sharp EL-W516 Calculator<br /><br /></b>The Sharp EL-W516's WriteView display uses multiple lines to display mathematics as it is seen on a page. Fractions are shown as fractions, exponents as exponents, integrals as integrals, and so on. This makes entering calculations easier, and reduces the chance of errors. <br /><br />At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers. <br />If you prefer to always get decimal results you need to <b>disable</b> <b>the WriteView display mode</b>. Doing this will make the calculator display like the Sharp EL-546W when in NORMAL mode. Answers will be given as decimals, but fractions will no longer look like fractions. In general, you will still need to follow the EL-W516 instructions.<br /><b>Disabling WriteView<br /></b><br />Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.<br /><br />There are now two options: 0: W-VIEW, and 1: LINE<br /><br />Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.<br /><br />To return to the WriteView display, go through the steps above but press 0 for W-VIEW.<br /><br /><b>NOTE</b>: It is not possible to have decimals as the default answer form when in WriteView mode. <br /></span>

How do you convert an answer in the form of a decimal into a fraction?


The TI-83 can only convert a decimal to a fraction if the denominator has no more than three digits.

Try . 5 MATH FRAC
Does that give you 1/2?

How do you convert decimal complex numbers in TI-84 (OS 2.53) to fractions?


I answered a similar question not long ago and here is what I wrote:

Not quite true for OS 2.56 MP for the TINspire with Ti84 keyboard. To convert a complex decimal value, that you just calculated, into a fraction use the command Math [1:>Frac] and it will convert the value to complex fractions
See below.

I suggest you upgrade the OS to version 2.55 MP.

Once you plug in a fraction problem and the calculator gives you a decimal as the answer, what button do you push to turn the decimal into a fraction?


It's not a single button. Press MATH to bring up the math menu, then press 1 to select the >Frac command.

Not all numbers can be converted to a fraction, for example if the denominator is more than three digits.

When i type in a decimal and then hit math and try to convert into a fraction, my calculator still shows the decimal as the answer. im pretty sure im doing it right but i dont know what is wrong. is there...


Yes, there is a feature or, setting in the mode that will stop you from converting fractions. Go to the mode screen by pressing the [MODE] key. [Down arrow] 9 times and, highlight and select the n/d by pressing the [ENTER] key. Next, [Down arrow] 1 time and, highlight and select Frac by pressing [ENTER] key. Just escape or, quit out of the mode screen and, the calculator should now be set up to convert your fractions. Just remember to go back and, change the last setting you made when you go back to dealing with decimal numbers.

Hey , how can i do percentage and fractions on the ti 84 plus silver edition ? Thxxx :D


There is no key nor command to calculate percentages. But that is easy to correct.

Percentages
To go from a decimal result to a percentage, move the decimal mark 2 places to the right. If you have no decimal mark as with integers, put a decimal mark at the end of the number pad it with zeros, then move the decimal mark 2 places to the right.
Ex: 0.73 in % gives 73.0%
Ex: 2.33 in % gives 233.00 %
Ex: 5 in % 5=5.00 becomes 500%

Fractions
The calculators has a command to convert a decimal number to a fraction. The command is called >Frac or To frac. You find it under the MATH key.

Enter a number (decimal or fraction)
Press [MATH][1:>Frac]
Command echoes on main screen after the number you entered.
Press [ENTER] the result is displayed as a fraction.
  1. If the number entered or stored in answer memory is a decimal number it will be converted to a fraction.
  2. If the number you entered is a fraction, the result will be displayed as a fraction but REDUCED to its simplest terms.
  3. For example 6/9 becomes 2/3
OS version 2.53MP

The TI 84PLUS and TI84PLUS Silver edition OS has seen a major upgrade to version 2.53 M(ath)P(rint). If you play a lot with fractions this new OS will allow you to do a lot more than what is described above.

Here is the link to download the new OS version. It cannot be transferred to a TI83PLUS or TI83PLUS SE.

How to us a fraction on the ti-83 calculator? I have home work due on this tues. and i dont know how to put a fraction in on this calculator .


Hello,

Ther e is no dedicated key to do that but ther is a command ToFrac noted as ->Frac. To access it use [MATH[1:->Frac].

Two ways of using the command.
1. You want to reduce a fraction to its simplest expression
27/48 [MATH][1:->Frac] [ENTER] gives the reduced fraction 9/16

2 You do not want your results converted to decimal numbers

(27/48) [x] (5/7) [MATH][1:->Frac][ENTER] multiplies the two fractions and gives a fraction as a result. 45/112

3. Your result is in decimal form and you want to cast it into a fraction. The conversion will be exact only for certain numbers. Results kept in fraction forms are more accurate than those represented as decimals.
Hope it answers your question.
