Question about Texas Instruments TI-83 Plus Calculator

I plug in square root of 1-4/9 and get the answer .7453559925 and select Math/1. Fraction but the calculator won't change the answer to fraction.

The Frac command only works if the number can be expressed as a fraction with no more than three digits in the denominator. Since the square root of 5/9 is an irrational number, it cannot be expressed as a fraction at all. The calculator is telling you that the value cannot be adequately approximated as a fraction with three or fewer digits in the denominator.

SOURCE: fractions

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.

SOURCE: I need some help please : )

The parenthesis is there so u can put a number under the radicle. Just close the parenththesis once u put the number under the radicle

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

1/6

SOURCE: TI-89 decimal to fraction

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.

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?

It's not a single button. Press MATH to bring up the math menu, then press 1 to select the >Frac command.

Not all numbers can be converted to a fraction, for example if the denominator is more than three digits.

The TI-83 doesn't really work with fractions. You can enter a fraction as a quotient. For example, one-third can be entered as (1/3) by pressing ( 1 / 3 ). However, the calculator works with numbers in decimal format. You can convert a result to a fraction by using the >Frac command, available by pressing MATH 1.

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,

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.

Hello,

Ther e is no dedicated key to do that but ther is a command ToFrac noted as ->Frac. To access it use [MATH[1:->Frac].

Two ways of using the command.

1. You want to reduce a fraction to its simplest expression

27/48 [MATH][1:->Frac] [ENTER] gives the reduced fraction 9/16

2 You do not want your results converted to decimal numbers

(27/48) [x] (5/7) [MATH][1:->Frac][ENTER] multiplies the two fractions and gives a fraction as a result. 45/112

3. Your result is in decimal form and you want to cast it into a fraction. The conversion will be exact only for certain numbers. Results kept in fraction forms are more accurate than those represented as decimals.

Hope it answers your question.

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

Place both the base and the exponent in parentheses

(3/4)^(-2) then press enter. Your answer will be in decimal form at first 1.777...

Press MATH

Select the 1: Fraction option and it will convert your decimal value to the fraction answer of 16/9.

Negative exponents flip the fraction. For instance, (3/4)^(-1) = 4/3. So for (3/4)^(-2) you could just square the numerator and denominator separately to get 9/16, and then flip the fraction to account for the negative. That will give you 16/9.
