To convert a **decimal** to a **percent**, multiply the **decimal** by 100, then add on the % symbol. An easy way to multiply a **decimal** by 100 is to move the **decimal** point two places to the right

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.

There is something wrong with your hand calculation.

40 multiplied by 6 is 240, which is close to 242, so 40 is close to 242/6. On the other hand, 4 multiplied by 6 is 24, which isn't even close to 242. Apparently you slipped a decimal point when you divided 240 by 6.

242/6 is 40 and one-third, or 40.333.... Rounded to one digit after the decimal point, it is 40.3.

Hi, Divide the top into the bottom number and you should get a decimal. 1/4 is .25 1/2 is .50 .....

To change the decimal in to to a fraction. Put the decimal over 100 and multiply.and then break that down.

In the default MthIO mode the calculator will always try to show exact or symbolic results. You can convert a single result to decimal by pressing the S--D key. If you want all results to be in decimal, press SHIFT MODE 2 to switch to the LineIO mode.

Step 1: Find a number you can multiply by **the bottom of the fraction** to make it 10, or 100, or 1000, or any 1 followed by 0s.
Step 2: Multiply both top and bottom by that number.
Step 3. Then write down just the top number, putting the decimal place in the correct spot (one space
from the right for every zero in the bottom number)
Example 1: Express 3/4 as a Decimal
Step 1: We can mulitply 4 by 25 to become 100

Step 2: Multiply top and bottom by 25:

**×25**
**3**
** = **
**75**

**4**
**100**
**×25**
Step 3: Write down 75 with the decimal place 2 spaces from the right (because 100 has 2 zeros);

Answer = 0.75

Example 2: Express 3/16 as a Decimal Step 1: We have to mulitply 16 by**625** to become 10,000

Step 2: Multiply top and bottom by 625:

**×625**
**3**
** = **
**1,875**

**16**
**10,000**
**×625**
Step 3: Write down 1875 with the decimal place 4 spaces from the right (because 10,000 has 4 zeros);

Answer = 0.1875

Example 2: Express 1/3 as a Decimal Step 1: There is no way to multiply 3 to become 10 or 100 or any power of 10, but we can calculate an**approximate** decimal by choosing
to multiply by, say, 333

Step 2: Multiply top and bottom by 333:

**×333**
**1**
** = **
**333**

**3**
**999**
**×333**
Step 3: Now, 999 is *nearly* 1,000, so let us write down 333 with the decimal place 3 spaces from the right (because 1,000 has 3 zeros):

Answer = 0.333 (accurate to only 3 decimal places !

Step 2: Multiply top and bottom by 25:

Answer = 0.75

Example 2: Express 3/16 as a Decimal Step 1: We have to mulitply 16 by

Step 2: Multiply top and bottom by 625:

Answer = 0.1875

Example 2: Express 1/3 as a Decimal Step 1: There is no way to multiply 3 to become 10 or 100 or any power of 10, but we can calculate an

Step 2: Multiply top and bottom by 333:

Answer = 0.333 (accurate to only 3 decimal places !

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,

To convert from decimal to fraction and vice versa pess the [S<->D] key. Alternatively, if one of the whole numbers (integers) has decimal mark (dot) the result will be decimal.

Hello,

To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.

Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

You should press SHIFT then MODE (setup). Then press 2. Done! If you want to change it back, just do the same again, but press 1.
