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

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

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

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

The MATH menu has two options 1:>Frac, 2:>Dec.

The first entered on the command line after a fraction keeps the result in (reduced) fraction form. On a displayed result, it converts a decimal into a fraction.

The second 2:>DEC converts a fraction into a decimal number.

The latest OS (2.53MP and following) has a better handling for fractions.

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.

The calculator has two Input/Output modes, MthIO and LineIO. In MthIO the results are displayed as fractions or as radicals or a mixture of fractions and radicals. What it means, is that in MthIO the calculator does exact calculations. Radicals in denominators are gotten rid of by rationalization, fractions are reduced to the same denominators before addition or subtraction. Fractions are reduced to simplest form.

In LineIO all results are displayed as decimal numbers.

If a result is exact (fractions and radicals) it can be changed to decimal form by pressing the S To D key, the one above the DEL key.

MthIO is the default IO mode. To set it, press SHIFT MODE and select 1:MthIO. To set LineIO as the IO mode, press SHIFT MODE and select 2:LineIO

Hello,

You get access the command by pressing [MATH][1: |->Frac].

If you want enter a fraction and keep it as a fraction (albeit a reduced one)

key in the number then the sequence [MATH][1: |->Frac]., then [ENTER].

Practice : 27/48 [MATH][1: |->Frac] [=] gives the reduced form 9/16.

While this fraction is still in [ANS] memory, you can press [MATH][2: |->Dec] [=] to get the decimal value 0.5625

Hope it helps.
