Question about Casio FX-115ES Scientific Calculator

When adding or subtracting decimals, the answer is given as an improper fraction. How do I fix this? I have tried but have been unsuccessful.

There is nothing to fix (It ain't broken). However if you do not like the display format, just press the [S<=>D] key and the result will magically be converted to decimals.

If you do not want any fractions nor radicals, JUST set the I/O mode to LineIO:

Press [SHIFT][MODE][2:LineIO]

Hi there,

There should be a button that says CHANGE - this will change it between mixed, improper fractions and decimals.

- 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.

If you have a key marked **[change]** press it to toggle from improper fraction to decimal to mixed number.

If you do not have the [change] key, press the** [a b/c] **key to change from decimal to mixed number. Press **[2ndF] [a b/c] **to convert to improper fraction.

Given two fractions a over b and c over d, you can subtract the first from the second by entering

( c / d ) - ( a / b ) ENTER

The calculator will give you a decimal result, which you can (probably) convert back to a fraction by using the >Frac command. Press MATH 1 ENTER

( c / d ) - ( a / b ) ENTER

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

In LineIO all results are displayed as decimal numbers.

Hello,

To make sure that results are always in decimal format, put a decimal mark (point) at the end of one integer.

ex:**1./2 or 1/2. **or** 1./2.** display as 0.5, so does **1. + 1/2**

To convert from decimal to fraction and from fraction to decimal press**a b/c**

To convert from proper to improper fractions use**[SHIFT][d/c] **

Hope it helps.
