How do I convert decimals to fractions on the TI Math Explorer (No numbers associated with it - i.e. TI - 15)?

See text below

The TI-83 can only convert a decimal to a fraction if the denominator has no more than three digits.

Try . 5 MATH FRAC
Does that give you 1/2?

I answered a similar question not long ago and here is what I wrote:

Not quite true for OS 2.56 MP for the TINspire with Ti84 keyboard. To convert a complex decimal value, that you just calculated, into a fraction use the command Math [1:>Frac] and it will convert the value to complex fractions
See below.


I suggest you upgrade the OS to version 2.55 MP.

To convert decimals into fractions in a TI-15 calculator you should do the following:

1) Enter the decimal number you wish to convert, for example: 0.075 and press ENTER.

2) Press the F<-->D button

It also works the other way around. There is a great Power Point presentation that resumes the basic operations of this particular calculator at NING published by EMRTs

The TI-83 can only convert a small range of numbers to a fraction. To try so, use the >Frac function on the MATH menu. Press MATH 1 to invoke it.

Hello,
Yes it can do fractions although it does not have a specific key.
If you want to enter a fraction and keep it in fraction form, though reduced to its simplest expression use [MATH][1:->Frac] [ENTER]
Exemple:
27/48 [MATH][1:->Frac][ENTER] displays the reduced form 9/16.
To convert a decimal number into a fraction (with the inherent loss of precision) press [MAT][1:->Frac][ENTER]
Use [MAT][2:->Dec] to convert to decimal, but this is done by default.
Hope it helps.

Hello,
Press [MATH][1:ToFrac] to convert an aswer to fraction.
If you enter 18.52[ToFrac] [ENTER gives 463/25

[MATH][2:ToDEC] converts a fraction to a decimal number.
Hope it helps.

Hello,
There is no fraction button. Any division of two integers you do is represented as a decimal number. If you want your fraction to remain a fraction you enter it as follows
7[ / ] 19 [ MATH][1:ToFrac] [=] displays 7/19
If you want to convert a decimal number into a proper fraction press [MATH][1:ToFrac] .
Exemple 7/19 [ENTER] gives .36842105. If without doing anything else, you press [MATH][1:ToFrac] you recover 7/19.
There are limitations related to the number of decimal digits in the floating point number.
.3684 [MATH][1:ToFrac][=] gives 921/2500 but
.36842 [MATH][1:ToFrac][=] gives .36842 : it is not converted to fraction.

Hope it helps

Hello,
Once you enter a fraction the calculator calculates it and displays a decimal result.So basically you cannot do fraction manipulations. However you can convert a decimal result into a fraction. To do the conversion, you enter the decimal number then you Press [MATH] and [1]. ( -->Frac) The number will be converted.
Similarly you can enter a fraction to a decimal number (-->Dec)
[MATH] [2:] [ENTER]. But I see no point in doing that, because any fraction entered is displayed as a decimal number.

Hope it helps

Press the MATH key to display the Math menu.

>Frac converts a decimal value to a fraction.
>Dec converts a fraction to a decimal value.
