Use the DMS key marked degree, apostrophe, double quotation mark.

Lets us call it [DMS]

To enter an angle in degree minutes seconds or hour, minutes, seconds, type in the number of degrees, press the [DMS] key, enter the number of seconds, press the [DMS] key, enter the number of seconds then the [DMS] key. Press = the calculator displays the value in DMS units. If you press the DMS key again the number displayed is converted to decimal degrees.

Example:enter 12 degrees, 15 minutes, and 25 seconds

12 [DMS]15[DMS]25[DMS] =

Calculator displays 12 deg 15'25"

Press the DMS key again and you see 12.2569444

Ih you want to enter a fraction or an improper fraction (numerator larger than denominator) you use the key n/d (numerator over denominator). For mixed numbers the key is **a b/c **or **u n/d, depending on manufacturer.**

The keys allow you also to convert from one representation to the other :**improper fraction to mixed number or mixed number to improper fraction.**

If the calculator can display math templates (Casio natural display, Sharp Write view or TI Multiview) pressing a b/c or u n/d displays 3 boxes, one alone, the 2 other stacked.

Use the fraction conversion features of the calculator.

Near (above) the [S<>D] key that toggles display between fraction/radicals and decimals, there is a marking that reads [a b/c <=>d/c]. Accessed through the [SHIFT] key, this key converts from improper fractions [a b/c] to improper fractions [d/c].

Enter your fraction with the fraction key (the one below the CALC key) and press enter. If the numerator is less then the denominator (proper fraction) the remainder is just the numerator. If the numerator is greater than the denominator the display will show an improper fraction (d/c) or a mixed number [a b/c]. Here a is the integer part and b/c is the fraction part.

So, if you have [a b/c] type display the remainder is b.

If the result is displayed as an improper fraction, use [SHIFT][S<>D] to convert the improper fraction (d/c) to a b/c.

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.

First put the calculator in degree mode.

To convert from fraction to a decimal number first enter your fraction or, mixed number. I'll convert a mixed number to a fraction first since, I don't have a key for the symbol that shows that a number is a fraction on my keyboard. Example: [3][A b/c][1][A b/c][2][A b/cd/e][ENTER]

3/2 should be entered at the home screen. While at the Home screen enter, [2nd][FD][ENTER]

1.5 should now be displayed at the Home screen.

As you can see it is really just using the [A b/c] key to enter in your fraction and, [FD] key to do the converting. The [A_b/cd/e] key isn't necessary because, mixed numbers will convert to decimal numbers just like fractions do. I just don't have the key to show a fraction symbol that the calculator uses. So to show that symbol, I used the / symbol with the fraction number.

Use the [a b/c] button to convert a displayed decimal number to a mixed fraction. If you want to convert further to an improper fraction press [SHIFT][a b/c] to access (d/c).

The sequence [SHIFT][a b/c] (d/c) toggles between improper fractions and mixed fractions.
