The EL-501X doesn't really work with fractions. You can always enter a fraction as a quotient. For example, you can enter 1/2 as 1 / 2, but you'll get 0.5.

<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>

This calculator is incapable of displaying simplified fractions (i.e. 1 ½), you will have to use the decimal value or contain your complex fraction in parenthesis. (i.e. (5/2).)

The calculator has two Input/Output modes: MathIO and LineIO.

LineIO

LineIO is the old way of entering numbers in calculators and results are always displayed as decimal numbers. Some calculators have a fraction feature and would convert a fraction to a decimal number and back.

MathIO

In MathIO you enter expressions as you would by hand or as you see them written in textbooks.

In this mode, results are by default displayed as fraction or fractions/ radicals.

Conversion

To convert the fraction/radical to decimals you just press the [SD] key. If you press again you cycle through all the available display formats.

So you can (if you want) use the MathIO to manipulate expressions and convert only the last result to decimal. By the way, fractions and radicals are generally more accurate than their decimal representations.

SetUP

If however seeing fractions and radicals is too painful, just set the LineIO as your default mode. To do so press [SHIFT][MODE] to open (SETUP), then select [2:LineIO]

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]

Here is what you do:

1) Press the Mode button.

2) Scroll down the list that appears until you find "Exact/Approx".

3) Change the setting for "Exact/Approx" to Exact.

4) Press enter to save the settings change.

You have three possible settings for "Exact/Approx":

1) Auto - The calculator will try to determine the best format.

2) Exact - The calculator will always give the answer in fraction form.

3) Approximate - The calculator will always give the answer in decimal form.

1) Press the Mode button.

2) Scroll down the list that appears until you find "Exact/Approx".

3) Change the setting for "Exact/Approx" to Exact.

Enter the fraction for example: enter 8/12.

The answer will be .666666

Then click Math (which is located under the Alpha button).

Click the ->Frac button (the first one).

It should come up as Ans->Frac.

Click Enter.

It should now read 2/3 which is 8/12 reduced.

Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition

go to mode and scroll down to exact/approx, exact will give fractions, approximate will give decimal, change it to approximate and press enter twice to save it, that should solve it, let me know of any other questions that you may have

Mar 21, 2008 | Texas Instruments TI-89 Calculator

To do fractions, just use the normal divide button.

To see the exact answer, hit MODE and scroll down to Exact/Approx and change to EXACT. In this mode, it will give the fraction always unless you press the special (green button with diamond) before pressing ENTER and it will give the approximate decimal value.
