Convert decimal fraction to binary


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.

Hi i have a TI-34-II and i need someone to tel me how to change a fraction into a percent and how to chance a fraction into a decimal. please help!!


One can express percentages as fractions. Say you have 60% and you want to change this into a fraction. you can also express this as 60/100 because all percentages are are parts of 100. So to change a fraction into a percent you would just convert the fraction into a decimal by dividing (3/4 = .75). Then to get the percentage you just multiply the decimal by 100 to get the percent. (75x100=75%

Convert 4 2/9 to a decimal


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 left-up-over-arrow.gif 3 = 75

4 100 left-under-over-arrow.gif ×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 left-up-over-arrow.gif 3 = 1,875

16 10,000 left-under-over-arrow.gif ×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 left-up-over-arrow.gif 1 = 333

3 999 left-under-over-arrow.gif ×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 !
