Fractions why i canot do fractins on my t-86 caculator

Use the words: decimal part, not decimal fractin
Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number
0.345 345 345 ... =345/999=115/333
In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator



Period is 345


Period is 1

Period is 09

Period is 79


In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of
0.d_1d_2...d_n d_1d_2... d_n ...=(d_1d_2...d_n)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.
Once the fraction is found, one should reduce it to its simplest form.

On the fx-115ES, to convert a single result to decimal press S--D. To have all results come out in decimal, press SHIFT MODE 2 to switch to the LineIO mode.

The >Frac command on the second page of the the MATH/Misc menu will display the current value as a fraction.

Because the TI84 does supports fractions in a funny way. Tap (3/4+1/2) then tap MATH and tap ENTER twice and you get the answer 5/4.
The TI 89 has a MODE called exact/approximate. In the exact MODE it does fractions; 3/4 + 1/2 = 5/4. In the approximate MODE it does decimals; 3/4 + 1/2 = 1.25

Hello,
You get access the command by pressing [MATH][1: |->Frac].
If you want enter a fraction and keep it as a fraction (albeit a reduced one)
key in the number then the sequence [MATH][1: |->Frac]., then [ENTER].

Practice : 27/48 [MATH][1: |->Frac] [=] gives the reduced form 9/16.
While this fraction is still in [ANS] memory, you can press [MATH][2: |->Dec] [=] to get the decimal value 0.5625
Hope it helps.

MATH 1 gives you the ->Frac command, which converts a decimal number to a fraction.

surround the fraction in parenthases.
1/64
would read (1/64)

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

When performing the calculations, put the fractions in parentheses. Then once you get your answer, press 2nd and Math (above the times button). Then press F5, MORE, and F1. It will have Ans Frac>. Then hit Enter and it'll change it to a fraction.

well I`am having a promblem with fractins and its hard for me to divid a fration
