Press the MATH button and use the FRAC> converter. note: this only works if the fraction is roundable to the nearest hundredth to form a normal difference. it will not work on complex numbers, variables, etc.

SOURCE: Changing result display from fractions to decimals

Struggled with this and found answer on about page 19 of the instructions on the Internet. Answer also appear on paper instructions under: "Displaying Calculation Results...etc just under "Note" Trick is you must have calculator in "LineIO" mode For setting MODE see "Calculation Modes & cal. Setup in paper instructions.

SOURCE: fractions appear when I divide; not decimals

press 'yellow key' then press 'enter' to see answers in decimal format instead of fractions

SOURCE: Is answering in fractions, and I'd like decimals.

what you do is click on the 'mode' button and go down to the 'Exact/Approximate' parameter and choose Approximate. hit enter and you're good.

SOURCE: fractions multiplied by fraction to get fraction

In the CATALOG there is a >Frac command that can be used with parentheses to multiply fractions.

(1/2)(1/3)>Frac

1/6

SOURCE: When I divide answers are always given in Fractions. Can I change it to come out in decimals?

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal

Decimal to fraction:
Type in your decimal (i.e. .5)
Then press [MATH] > press [ENTER] on [>FRAC]
Then press [ENTER] again
Example:
.5>Frac
1/2
For a fraction to decimal:
Simply type in the fraction and press [ENTER]
Example:
1/3
.33333333333
(*Note that the decimal value is truncated to fit the screen)

Hope that helps! Have fun calculating!

To change a decimal to a fraction using the TI 30, insert your decimal number, then press [2nd][PRB].(the PRB button says F<>D above it for Fraction <> Decimal)

To convert a fraction to a decimal or a decimal to fraction you use the [a b/c] key.

While converting a fraction to a decimal number is always possible, converting a decimal to a fraction may, at times, not be possible.

To convert fractions to decimals, and decimals to fractions use the [a b/c] key. If the total number of symbols (num, denom, fraction bar) to display a fraction exceeds 10, the fraction is automatically converted to decimal format.

If you enter an improper fraction or a mixed fraction with the the [a b/c] key it will be displayed as a fraction. This result being displayed you can press the [F-D] key to convert the fraction to decimal. If you do nothing else and you press the [F-D] key again, the original fraction will be restored.

However, it seems that you cannot enter an arbitrary decimal number and convert it to a fraction. The [F-D] key seems to work one way : from a fraction to a decimal number. You will only recover a fraction if the original number was a fraction.

Hello,

When you have a fraction output, press the [S<->D] key to convert to decimal, the same key to convert from decimal to fraction. Beware that fraction results are exact, while decimal values are approximate.

However if you cannot stand the sight of a fraction, there is a way to get rid of this type of output.

Here is how you do it.

[SHIFT][MODE][2:LineIO]. All your results will be in decimal. However you will lose a lot of functionalities, such as calculating the logarithm in any base, manipulating radicals.

My advice, if you allow, is to activate the [SHIFT][MODE][1:MathIO] and press the [S<->D] whenever you want a result (be it a fraction or radical) in decimal format.

Hope it helps.

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] **

Hello,

Press [MATH][1:ToFrac] to convert an aswer to fraction.

If you enter 18.52[ToFrac] [ENTER gives 463/25

[MATH][2:ToDEC] converts a fraction to a decimal number.

Hope it helps.

Hello,

Once you enter a fraction the calculator calculates it and displays a decimal result.So basically you cannot do fraction manipulations. However you can convert a decimal result into a fraction. To do the conversion, you enter the decimal number then you Press [MATH] and [1]. (** -->Frac)** The number will be converted.

Similarly you can enter a fraction to a decimal number**(-->Dec)**

[MATH] [2:] [ENTER]. But I see no point in doing that, because any fraction entered is displayed as a decimal number.

Hope it helps
