Fractions i want to make a mixed number on mine and put fractions into simpilest form?

Check that picture

Multiplying Fractions:

1. Make sure you're working with two fractions.
2. Multiply numerator x numerator, then multiply denominator x denominator.

Dividing Fractions:

1. Make sure you're working with two fractions
2. Flip the second fraction upside down.
3. Change the division sign into a multiplication sign.
4. Multiply top x top and bottom x bottom.

Converting Mixed Numbers into Improper Fractions:

1. Convert mixed numbers into improper fractions.
2. Take the whole (non-fraction) number and multiply it by the denominator.
3. Add that answer to the numerator.
4. Put that amount over the original denominator and you will have an improper fraction.

Method for Adding and Subtracting Fractions:

1. Find the lowest common denominator (bottom number). For both adding and subtracting fractions, you'll start with the same process.
2. Multiply fractions to match the lowest common denominator.
3. Add or subtract the two numerators (top number) but NOT the denominators.

Convert the mixed numbers into improper fractions, and multiply the improper fractions. Do not forget to reduce the product to its simplest form.

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.

The key marked [a b/c], the one below the [X,Theta,T] and [7], allows you to enter fractions either as mixed numbers or improper fractions.
To enter the mixed number 3 4/7 you key in 3 [a b/c] 4 [a b/c] 7 [EXE]
To convert this to an improper fraction press [SHIFT] [F--D].
Pressing the [F--D] key toggles between fraction and decimal representation.

You do not simplify fractions on the calculator. If the calculator is able to display fraction results, be sure that the form it gives you is the simplest. If the fraction is a mixed one there is usually a key to switch from mixed to improper, and from improper to mixed the keys are [a b/c] and [d/c]

Calculation results will be displayed using
fractions, r, and ?. When you press CHANGE, the display will cycle
through the following display styles:
• Mixed fractions (with or without ?) ? improper fractions (with
or without ?) ? decimal numbers
• Proper fractions (with or without ?) ? decimal numbers.

Upgrade the OS of the calculator to the 2.53 MP (Math Print) version. As you can see on the following screen capture of the MODE setting, you can choose to use the CLASSIC option (the old way) or the MathPrint version.
You should notice that the Answers AUTO DEC or FRAC options allow you to configure the calculator to work in DECimal, FRACtions or AUTO (the calculator chooses whats is appropriate).
The n/d is for improper fractions and Un/d for mixed fractions.

Enjoy your new found freedom.



Here is the link to the new OS 2.53MP

for my 82 i put my fraction in parentheses then press MATH and scroll to >FRAC

When you get a fraction for he answer: shift-S<->D[a b/c<->d/c]

This way, you change it to a mixed fraction or improper fraction
