Im working on my math homewrok and i need to turn a decimal into a percentage but it has a fraction in the answer i cant figure out how to do it on my calculator it is a texas instrument TI-34 II. PLease help?

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.
Calculate the factor (f) for making the decimal number an integer:
f = 10 to power d
Example: f = 10 power 2 = 100
Multiply and divide the decimal number x by the factor f:
x * f / f = y / f
2.56 * 100 / 100 = 256 / 100
Find the greatest common divisor (gcd) of the fraction.
gcd(256,100) = 4
Reduce the fraction by dividing the numerator and denominator by the gcd value:
256 / 100 = (256/4) / (100/4) = 64/25
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
<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>
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.
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.
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.
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 . ( -->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.
