Hello, the title say everything. What is the key to reduce fractions, example: My fraction is 50/100, when I reduce the fraction become: 1/2.
I really need to know how, because I have big fractions to reduce.
Thanks and have a nice day

Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
Calculate the factor (f) for making the decimal number an integer:
f = 10 to power d
Example: f = 10 power 2 = 100
Multiply and divide the decimal number x by the factor f:
x * f / f = y / f
2.56 * 100 / 100 = 256 / 100
Find the greatest common divisor (gcd) of the fraction.
gcd(256,100) = 4
Reduce the fraction by dividing the numerator and denominator by the gcd value:
256 / 100 = (256/4) / (100/4) = 64/25
One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25
To input fraction on a TI83PLUS you enter a numerator, press the division key thaen the denominator. But before pressing the ENTER to execute the command, press the MATH button. In the new screen that displays, select the option 1:>Frac. At this point your comiand line has [numerator] [/] [denominator] [>Frac]. Press ENTER to valodate. The fraction entered will be kept in fraction format but reduced to its simplest terms.
If you have a TI84Plus, then the newer OS (2.43MP ) handle fractions much better than OS 1.19 of the TI83Plus.
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.
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, 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.
If you call a simple addition a problem it is no wonder that everything seems so difficult. When you calculate the sum 6.11 +6.11 , the calculator gives you a fraction reduced to it simplest terms, 611/50. The result is correct, but it happens that you want it
expressed as a decimal rather than a fraction. To fix that all you have
to do is to press the button [S<->D] above the red [DEL] key. It allows you to toggle the display format between fraction and decimal. 611/50 [S<->D] changes display to 12.22 and if you press the key again you go back to fraction 12.22 [S<->D] 611/50
if you enter square root of 2 and it displays as a radical, you convert
it to a decimal by pressing the key [S<->D].
and radical formats allow you to do exact claculations. But if you do
not want to hear about that you can just press [SHIFT][MODE][2:LineIO]
: Your calculator will do things the old way, but you will lose some
important functionalities. My suggestion is to set the default mode
[MathIO] by pressing [SHIFT][MODE][MathIO] and to press the
[S<->D] key to convert to decimal.
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.
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
