The fraction 711/22 is an improper fraction (the numerator is greater than the denominator).

While there is nothing incorrect about this, an improper fraction is typically simplified further into a mixed number.

The whole number part of the mixed number is found by dividing the 711 by the 22. In this case we get 32.

The fractional part of the mixed number is found by using the remainder of the division, which in this case is 7 (711 divided by 22 is 32 remainder 7).

The final answer is: 32 7/22

To manipulate mixed numbers (not mixed fractions) one usually converts them to improper fractions then operate on them.

Here it is rather simple

9 4/7- (2 3/14)=(9+8/14) -(2 +3/14)= (9-2) +(8/14 -3/14) =7 5/14

Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

Example

(2 1/3)*(1 5/7)=?

Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3

Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7

(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)

The 7's in the numerator and denominator cancel one another leaving

12/3=4

**(2 1/3)*(1 5/7)=4**

Not all products of mixed numbers will give a simple result as this one. More likely they will not.

Example

(2 1/3)*(1 5/7)=?

Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3

Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7

(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)

If the result is positive, type in the integer part then add the fraction part either with the help of the fraction key or the division key. (I do not think that the TI82 has a fraction key.

If it is anything like the TI3 there is command under MATH >Frac. It should be pressed after you enter the mixed number to keep the result as a fraction.

If the mixed number is negative you enclose the whole number in parentheses. Press the change sign (-) key to negate the result.

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.

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.

Hello,

You add them normaly, not worrying about the display**until the final result.** Then you press [2nd][c/d] and it will converted.

Hope it helps

if you want to use your calc for this you would have to put it in as the operations to change the mixed to improper fraction i.e. input exactly as "((8*3)+6)*((3*7)+1)=" remember? take denominator times whole number plus numerator and put over denominator to convert from mixed to improper... hope this helps

Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer
