2.) 0.32

On the home page put 4.5 and press enter. Then hit "2nd" and "x" to get the "Math" window up. After that hit F5(Misc). Then hit "More". Finally, hit F1(Frac) and press enter. You should get the number (9/2). Repeat the same steps for 0.32.

SOURCE: fractions appear when I divide; not decimals

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

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

Hello,

Use the [2nd][MATH] keys. Scroll right [F6] to the softmenu [->Frac or To Frac].

Hope it helps.

You haven't made the purpose of the question very clear Miriam so I am only guessing that it is an exercise in rounding or shortening decimal fractions to make them easier to work with which is often convenient when approximations do not matter.

The general rule of rounding is to take the last figure and if it is less than 5 it is erased and if it is 5 or more it is erased but 1 is added to the next or the new last figure and the process is repeated until the fraction is shortened to the required length.

If you take the decimal fraction 0.8745, after the first stage of rounding it would become 0.875 and then after the second stage of rounding it would become 0.88 and then finally rounding to one decimal place the result would be 0.9.

I hope this helps you deal with your fraction. I apologise in advance if I have misunderstood the question.

You can keep a certain number of decimal digits and ignore the others, or you can use the original ratio (fraction) because it is exact.

0.5 repeat, that is 0.5 followed by an endless string of 5's. Normally this is written as 0.5 with a heavy dot over the 5, but I can't do that here.

A number with a periodic decimal representation cannot be equivalent to a fraction with denominator 10 (or a multiple of 10) except if the repeating decimals are zeros.

0.454545...=45/99=5/11

0.454545...=45/99=5/11

At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers.

If you prefer to always get decimal results you need to

Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.

There are now two options: 0: W-VIEW, and 1: LINE

Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.

To return to the WriteView display, go through the steps above but press 0 for W-VIEW.

Say you have a repeating decimal number 0.714285 714285 714285 etc. You identify the period (the repeating part) and in this case it is 714285.

You count the number of decimal places in the period: here it is 6. Your equivalent fraction is

Fraction= period/(99...9) where the number of 9's in the denominator is equal to the number of decimal places in the period. For this case, that is 6.

Thus

0.714285 714285 714285 etc.= 714285 / 999999

Reduce the fraction and you will find 5/7

This technique works for a repeating decimal number where the period starts just after the decimal mark.

If the periodic part does not start right after the decimal mark there are modifications to be made.

You can convert a decimal value to a fraction by using the >FRAC command in the MATH MISC menu. Be aware that this command will not work on all values.

Answer is 39 over 23......or 1 and 16/23. Check your settings on the calculator. People are running into this problem with decimals and there is an easy fix.

Let's say you have a repeating decimal such as .16666.....If you type in .166 or .1666 or .16666 and check as fraction it will NOT work. Reason why is you haven't typed enough of the "repeating" numbers for the calculator to understand that it is in fact "repeating." If you have a single number ie. 1-9 you must type in a minimum of 11 of that number. Then it WILL work as fraction.

Let's say you have a 2-digit number such as 13. Then you need to type in at least 6 of that number. Say you want to convert 1.2181818 where 18 keeps "repeating." Well I only typed it in 3 times. It won't work to convert. But type in that repeating number 6 times and it will.

Again calculator need to know that it is in fact repeating. Only typing it in a couple times could still change the outcome so it will basically fail to show the fraction until it knows for sure.

Hello,

You may have guessed right. The presence of the parentheses makes the content of the parentheses evaluated first. So there is a loss of precision.

On the Ti92 I do 7*(-1/7)+1 and find 0.

But with Floating mode set at 12 decimal digits I get

1/7.=.142857142857.

Then .142857142857.*(-7) + 1 gives 2E-14.

Try to calculate pi*(-1/pi) +1 or e*(1/e)+1.

Hope it answers your question.
