1 Answer

The calculator won't convert fractions into decimals

If i enter 3 divided by 5 the answer ends up the same and does not calculate the answer into decimals like. To me the answer should show up as .6 but instead the answer is the same as what i asked it to calculate.

When you are dividing two whole numbers but you need the answer to be in decimal form, how many numbers after the decimal need to remain especially when there many


It depends on what you need. If you divide 100 by 3 you'll get 33.333333333333333333333333333333 and a lot more 3's.
If you need it to be 2 decimals behind the comma your answer will be 33.33 if you want it to be 3 decimals you'll just end up with 33.333 etc. etc.

So it completely depends on what you need to calculate.

Your Texas Instruments calculator has a built-in printer for producing a permanent record printout of
your calculations with negative numbers printed in red. A big, easy-to-read display also enables you to
check entries or perform quick calculations without printing.
GETTING STARTED

3. Fit the roll of paper on the holder so that it unrolls from the bottom, with the loose end toward the
calculator.
4. Cut the end of the paper squarely and insert it firmly into the printer slot on the back of the
calculator.
5. Press & until the paper is in the printing position.
Replacing the ink roller (see illustrations 5 and 6 on page ii)

When I divided a problem EX. 3/2 the calculator will not answer in decimal


Hi,
You are not dividing problems, you are dividing number. This said, there is a simple way to ensure that the results of divisions are displayed in decimal form: It consists in putting a decimal mark (decimal point) at the end one integer (whole number)
ex:
3/2. gives 1.5
3./2 gives 1.5
3./2. gives 1.5

You can also configure your calculator to display all numerical results in decimal format. To do that press [MODE][F2]. Use the down arrow to select the ligne Exact/Approx, then use the right arrow to unfold the menu options 1:Auto
2:Exact
3:Approximate
Select 3:Approximate and press [ENTER]

When I try to divide numbers that would leave a remainder like 1 divided by 6 which should give me an answer like 0.16666666666 instead all it says for an answer is 1/6. it does say in the manual to input...


Hello,
To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.
Dans ce cas 1/6 is displayes ase 0.167.
Hope it helps.
