Question about Texas Instruments TI-34II Explorer Plus Calculator

The subject pretty much says it all. The manual says something about choosing your own factor but I guess I don't get it. I keep getting a domain error.

Thanks,

Rick

To get the answer in fraction you need to use fraction only and if you use at least one not fraction number like 0.3125 the answer won't be in fraction too, sorry.

Rate me, thanks.

A mixed number is a number composed of an integer (whole) number and a proper fraction, one that has a numerator less than the denominator. Example 2 1/3 =2+ 1/3. 2 is the integer part, and 1/3 is the proper fraction part.

Certain fractions can be simplified further because the numerator and denominator share a (common) factor. By cancelling the common factor in the numerator with the factor in the denominator,

one gets a fraction with smaller numerator and denominator.

For example the percentage you provide 0.15% can be converted to 15/10000.

Since 15 and 1000 are both multiples of 5, the number 5 is a common factor in both. 15=5*3, and 10000=5*2000

Cancel the two 5 (simplifying by 5) in numerator and denominator leaves 3/2000. Thus

0.15%= 0.15/100=0.0015=3/200

I hope that this makes sense to you.

divide both the numerator and the denominator by 2 (a common factor)

16/2 8/2 4/2 2

---- = ----- = ----- = -----

24/2 12/2 6/2 3

16/2 8/2 4/2 2

---- = ----- = ----- = -----

24/2 12/2 6/2 3

When you enter a fraction using the fraction key, the displayed fraction is always reduced (simplified). By hand, you look for common factors in the numerator and denominator then simplify by them. Keep looking for common factors and simplifying until there are no more common factors.

If you enter the ratios using the fraction entry key ( [a b/c] the results will be displayed as fractions. And when the calculator displays fractions they are always in their reduced form.

In general, when you are manipulating fractions ( Pi/2 is no a fraction even if you write it as one) you can try to simplify them by looking for the greatest common factor (GCF) of the numerator and denominator. When you simplify by the GCF the fraction that is left is in its reduced form.

A fraction is in fact a ratio of two number: a division of a numerator by a denominator. The key used for the division operation is the one above the multiplication sign and below the caret [^], and in thee rightmost column of keys.

Beware that this calculator converts any ratio of two numbers into a decimal value. To keep a fraction in a fraction form you must use the [|=>Frac] or [ToFrac] command. To convert a decimal result to a fraction, use the [|=>Dec] command.

These commands are accessible through the CATALOG or more easily by pressing [MATH] (under the ALPHA key) and selecting [1:|=>Frac], or [2:|=>Dec]

Ex: to keep 27/48 in fraction form you enter

27 [/] 48 [MATH][1:|=>Frac] [ENTER]. Result is 9/16

You will notice that the resulting fraction is reduced to its simplest form.

To convert the above result from fraction to decimal press [MATH][2:|=>Dec]

A fraction can always be approximated by a decimal value but the converse is not always possible.

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,

**I will show you the steps. You should be able to carry them out.**

1. Get rid of the 5 on the left by transferring it to the right, while obeying the rules.

2. Write the right side as a fraction with 16 as denominator.

3. Calculate 4^3.

4. Get rid of the number that multiply x by transferring to the right side, while obeying the rules.

5.Express the right hand side as a fraction reduced to its simplest form (Hint:a factor 16 will simplify).

6. Give the result as fraction or calculate its decimal value if that is what is asked.

Hope it helps.

Enter the fraction for example: enter 8/12.

The answer will be .666666

Then click Math (which is located under the Alpha button).

Click the ->Frac button (the first one).

It should come up as Ans->Frac.

Click Enter.

It should now read 2/3 which is 8/12 reduced.

Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition

Yeah, there isn't a fraction button on an 84. You have to enter it manually as 4/9 or if simplifying a decimal, use the Ans>Frac under the MATH menu
