Question about Texas Instruments TI-30 XIIb Calculator

# Sharp scientific calculator

I have a fraction question. If I enter 1/8 and then =, I of course get .125. My question is, how do I go the other way? If I enter .125, what key do I press to get the fraction, 1/8?

There is a button that switches answers from fraction to decimal and decimal to fractions. It is hidden under the PRB(probability) button and is labeled F<>D. Push [2nd] PRB to get to it. For your example, you would enter .125 [2nd] PRB then enter and you get 1/8.

To get an improper fraction(27/2) to a mixed number and the other way around. Use the same process as above except you push use the button hidden under the A b/c button.So 27/2 would become 13 1/2.

### 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 to calculate fractions in hp 50g

For such a sophisticated calculator (computer) a simple thing like entering a fraction seems too difficult to explain. There are a great number of scientific calculators that handle fractions easily.
Anyway, to manipulate fraction without their being calculated numerically, you must use the CAS.
Press MODE then F3 CAS.
In the CAS screen, move cursor to the _numeric option. If it is cheked, uncheck it by pressing F3:Check.
Press OK to exit the CAS configuration screen. Press OK again to exit the MODE screen.
You can know enter fractions using the division key (Z)
If you type 1/5 + 13/7 you will see 72/35

Now if you enter 1/5 then press the ENTER key you will see 1/5. But if you add to that 13/7 you will see 1/5+13/7 and the result will not be calculated. To calculate the resulting fraction you must press EVAL (Green Left Shift ANS) ENTER.
As you can see, this is not the most efficient way to handle fractions.

### How can I solve a fraction like 1/2 plus 9/3 on a scientific casio fx-991MS calculator?

Use the [a b/c] key to separate the elements of a fraction.
To enter 1/2 : press 1, press [a b/c], then press 2

1/2+ 9/3 : 1[a b/c]2 + 9[a b/c] 3 [=]
By the way, why do you keep 9/3 as a fraction when you can have it as an integer? Not that it makes a difference to the calculator.

### Fractions

I checked the manual for the EL-501W calculator and I found out that it does not do fraction calculations. However yours may be able to. Look for a key labeled [a b/c] and a [2ndF] key [d/c].

If you have them then you can calculate with fractions.

The way to use the [a b/c] key is as follows
15 [a b/c] 7 [a b/c] 19 [a b/c] should allow you to enter 15 and 7/19.
A mixed fraction can be converted into an improper fraction by pressing [2ndF][d/c]
