Sorry, you have to be more specific. How many decimals are repeating.
If your number is 6.32323232... the period is 32.
Decompose the number in two parts 6 and the repeating part. 0.323232 =0.32
0.32 repeating = 32/99
Your number will be 6+32/99= (6*99)/99+(32/99)= (6*99+32)99=626/99
It is irreducible.
What is important to remember is that
0.abcd where a,b,c,d are the digits that constitute the period can be written as (abcd)/9999
period/ (as many 9 as there are places in the period
0.435867 =43587/999999
Also 0.999999999999.....=1
0.11111...=1/9
0.09090909....=1/11

Struggled with this and found answer on about page 19 of the instructions on the Internet. Answer also appear on paper instructions under: "Displaying Calculation Results...etc just under "Note" Trick is you must have calculator in "LineIO" mode For setting MODE see "Calculation Modes & cal.

you can also go press the 'mode' button, and go down until you're at 'Exact/Approx' and choose '3: Approximate'
SOURCE: fractions multiplied by fraction to get fraction
In the CATALOG there is a >Frac command that can be used with parentheses to multiply fractions.
(1/2)(1/3)>Frac

Hello,
Use the [2nd][MATH] keys. Scroll right [F6] to the softmenu [->Frac or To Frac].
Hope it helps.

Here is what you do:
1) Press the Mode button.
2) Scroll down the list that appears until you find "Exact/Approx".
3) Change the setting for "Exact/Approx" to Exact.
4) Press enter to save the settings change.
You have three possible settings for "Exact/Approx":
1) Auto - The calculator will try to determine the best format.
2) Exact - The calculator will always give the answer in fraction form.
3) Approximate - The calculator will always give the answer in decimal form.
