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.

The fraction button is usually marked [a b/c]. Its shifted function [d/c] converts a mixed number into an improper fraction.

To enter a mixed number, say 7 3/5

Enter 7, press the [a b/c] key, enter 3, press the [a b/c] key, enter 5. Press =/EXE

The EL-501 doesn't display fractions. Some of Sharp's other calculators do, but not this one.

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.

If you are using a Sharp or Casio scientific calculator and you would like your answer to be shown as a fraction, simply hit the [ab/c] button after you have entered your calculation.

For example:

15/6 = 2.5

press [ab/c] and your screen will show 2/1/2 which means 2 and 1/2.

15/6 = 2.5

press [ab/c] and your screen will show 2/1/2 which means 2 and 1/2.

Use parenthesis.

1.06 [2nd] [ DEPR ] [ ( ] 1 [ / ] 4 [ ) ] [ - ] 1

2nd [ DEPR ] should be x^y or the exponentiation function.

1.06 [2nd] [ DEPR ] [ ( ] 1 [ / ] 4 [ ) ] [ - ] 1

2nd [ DEPR ] should be x^y or the exponentiation function.

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.

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]
