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.

You have to be careful. 80% is in fact 0.8.

Turn the calculator ON.

Enter the number 0.8

If your calculator is set to Write-View you will see the number displayed as a stacked fraction 4/5. If it is already in this form, press the key marked**change** with two arrows. The display should show a fraction.

If your calculator is set to LINE, you will see 4r5, where 4 is the numerator and 5 is the denominator.

**The key marked change allows you to change displayed result from decimal to fraction and from fraction to decimal. When a number is converted to a fraction, it will always be a fraction reduced to its simplest terms.**

To configure the calculator to do fractions, set the Input/Output mode to MathIO.

**Press [SHIFT][MODE] to open (SetUp) then select [1:MathIO]. **

After you set it to MathIO, pressing the fraction key will display a fraction template where you can enter numerator and denominator as you would by hand (horizontal fraction bar). Also, the calculator will display results as fractions and radicals**whenever possible.**

To perform arithmetic operations on fractions use the regular operation keys (x, +, -, /). The calculator will perform the operations and display the results as fractions** (whenever possible).**

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).)

Hi eamon at hom,

Doing fraction on the Sharp El 531W really isn't that bad. I had to use pictures because, the symbols will not transfer over to your posting for me to show you. When you select the [ON/C] this clears the calculator of previous calculations and, data so that they won't interfere with your new calculations.

Let take the first example where a mix number is being added to a improper fraction. Because I used the [a^b/c] key this makes the calculator display the answer in a mixed fraction format or, a proper fraction format. If I press the [a^b/c] key again after the answer the format will change to a decimal format. The fractional formats are displayed in a mixed number, improper or, proper fraction formats. A improper fraction is really a proper fraction number with the top number (numerator) is greater than or equal to the bottom number (denominator).

[ON/C] [3] [a^b/c] [1] [ [a^b/c] [2] [+] [4] [a^b/c] [3] [=] mixed number results. Now let's do the same calculation as a improper or, proper fraction format.

[ON/C] [7] [a^b/c] [2] [+] [2] [a^b/c] [3] [=] still a mixed number result. Even though I enter the fractions in a improper and, proper fraction formats the calculator will still display in a mixed number format. This is because the calculator first displays as a mixed number if it can. If it can't then it will display the value as a proper fraction and, never as a improper fraction. To convert from a mixed number to a improper fraction format if the calculator did not convert it to a proper fraction, I have to use [2ndF] [d/c] keys on the command line.

This show a little more complex raised power use of the [a^b/c] key.

This shows the [2ndf] [x^-1] keys being used to calculate fractions.

When I first saw this question being asked it, was answered with just use the / command. Which that isn't really a good answer because, in math we like to use elimination. If you use the / command eventually the numbers are going to be rounded off and, your not going to be able to eliminate anything. If you have any further question on how to preform fractions with this calculator be sure to post your comment and, I'll be glad to help.

ok i figure this is like any other calculator, but without a fraction button. A fraction i somthing / something . so instead of the fraction button use the division button.

A fraction is just a number like (almost) any other. On most calculators, as you enter 6/5 the calculator displays its decimal value. When you press - the calculator waits for a number 2 then / then 5. Once you press the equal sign it will calculate 2/5 then subtracts it from the preceding result. The priority rules favor multiplication and division over addition and subtraction.

On some calculators you can keep a fraction in fraction format and operate on it with other fractions, and the result may be obtained as a fraction.

The gist of the story is that ON A CALCULATOR operations on fractions as performed like operations on any number.

The fraction symbol is ab/c

All scientific/graphics calculators have a fraction key. Going by the picture I would assume that calculator would have it

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]

In the CATALOG there is a >Frac command that can be used with parentheses to multiply fractions.

(1/2)(1/3)>Frac

1/6

(1/2)(1/3)>Frac

1/6
