Question about Texas Instruments Office Equipment & Supplies

The way it works is as follow. If a result is displayed as a fraction you can convert it to its decimal representation. **If you do nothing after the conversion**, you can revert the decimal representation to the fraction.

None of these solutions answer his question. When converting a fraction or any number with decimal places to Binary, the TI-89 gives "Error: Domain error." For example, entering .6875 [2ND][MATH][BASE][BIN] does not work. I haven't found a way to do it with built in functions. In order to do these types of conversions, I use the following method.

Convert: 0.6875 to Binary

- left of decimal is a 0, so write down a 0, then a decimal point: (0.)

- multiply .6875 x 2 = 1.375 left of decimal is 1, write a 1: (0.1)

- drop the 1 and multiply .375 x 2 = .75 left of decimal is 0. write a 0: (0.10)

- multiply .75 x 2 = 1.5 left of decimal is 1, write a 1: (0.101)

- drop the 1, multiple .5 x 2 = 1. left of decimal is 1, write a 1: (0.1011).

- since there is no more fraction, the final answer is (0.1011). Hope this helps.

Sad as it may be, this calculator does not have a % button/key/menu. So do not look for it. However you can still convert your decimal numbers to percent values.

1 %= 1 per cent (100) = 1/100=0.01

0.01=0.01*100/100=(0.01*100)/100=1/100=1%

To convert a decimal number to %, move the decimal mark two places to the right.

To convert a percent value to a decimal value, move the decimal mark two places to the left and drop the % symbol.

75%=0.75

135%=1.35

The following examples will demonstrate how to
convert decimals into fractions using the TI-30Xa and TI-30Xa Solar.
Please be aware that TI-30Xa Solar School Edition calculators do not
have this functionality.

**Example**: Convert .25 to 1/4

- Input .25, press [2nd][<--] (says F<>D above it).

**** F<>D means fraction to decimal, decimal to fraction. **

**Example**: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

**Example**: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

- Input .25, press [2nd][<--] (says F<>D above it).

- Input 1.38, press [2nd][<--].

- Input 9.75, press [2nd]{<--].

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.

You can always convert a fraction to a decimal. The reverse may not always be possible. Look at the example on the screen capture.

You may be lucky and recover a fraction you have just converted into decimal format, but you cannot just write 0.333333333333 and expect the calculator to convert it to 1/3: The true fraction 1/3 has an infinite number of 3's after the decimal mark.
