Question about Texas Instruments TI-30XA Calculator

Re: fractions

What are you guys talking about?

The TI-30XA has a 10 digit display, so you can enter up to 10 digits for the numerator and 10 for the denominator before hitting "="

Hi Anonymous,

You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount, but only multiply or divide, never add or subtract, to get an equivalent fraction.

I've only shown the fraction part of your question as 1 is a whole number.

1/2 = 2/4, or 4/8, or 8/16 or 16/32 or 32/64 & so on.

Going the other way, dividing 2/4 by 2 will give 1/2.

But, only divide when the top and bottom would still be whole numbers, for instance you wouldn't use divide for odd number fractions, for example 1/3 or 3/5 etc.

Trust this helps, best regards Alan

A proper fraction is one where the numerator is less than the denominator 1/3, 2/3,1/4, 5/9. All these values are less than 1.

Take now the fraction 17/8. This is not a proper fraction because the numerator is NOT less the denominator. The result can be written as a mixed number**(2 1/8) ** or an improper fraction **(17/8)**

By hand you can write every integer you wish as a fraction with denominator 1. 4=4/1, 13=13/1. You can even generate all the equivalent fractions of any integer, for example -4=(-8/2)=8/(-2)=-8/2=-12/3=...

However, simple calculators are designed with a feature called automatic simplification. That is why ever result that is a fraction that is equivalent to an integer is written as that integer. Fractions are reduced to their simplest form.** Call it a design flaw if you want but that is how it is.**

Decimal to fraction:
Type in your decimal (i.e. .5)
Then press [MATH] > press [ENTER] on [>FRAC]
Then press [ENTER] again
Example:
.5>Frac
1/2
For a fraction to decimal:
Simply type in the fraction and press [ENTER]
Example:
1/3
.33333333333
(*Note that the decimal value is truncated to fit the screen)

Hope that helps! Have fun calculating!

To Enter a basic fraction just enter the first number, then a division sign, then the second number. So two thirds would look like "2/3" (Without quotes). For more complicated fractions you may need to put parentheses for the left and/or right of the division sign like in the fraction (5+2^4)/(2-8). To get the calculator to show it as a fraction you would enter the fraction, then press (Math) then (1:Frac). So the input on your screen should look something like this "2/3>>Frac" (Without Quotes, and >> being a filled triangle pointing at the word Frac). From your post it sounds like you were putting the fraction last when it should have gone first.

Hello,

You add them normaly, not worrying about the display**until the final result.** Then you press [2nd][c/d] and it will converted.

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
