Hello,
The Ti83 evaluates every everything entered as a decimal number by default. However if you want to keep a fraction as a fraction you should follow it by the sequence [MATH][1:|=>Frac].
So if you enter the fraction
27/48 [MATH][1:|=>Frac] [ENTER] the calculator displays the reduced form 9/16.
So you can keep fractions as fractions, albeit reduced ones, by following them with [MATH][1:|=>Frac], before hitting [ENTER]

Hope it helps.

Texas Instrument has released a major update to the TI84PLUS/SE. This
update numbered 2.53MP introduces Math Print that displays fractions as
one sees them in textbooks. Installing it will allow the user to
manipulate easily fractions (mixed numbers, improper fractions )
calculate logs in arbitrary bases, configure the calculator to convert
automatically fractions to decimals, etc. It is WORTH installing.

Enter any fraction as a division problem and your TI 83 will evaluate it as a fraction.

For instance, 3/4 = three fourths.

### How to turn 85.4 into a mixed fraction

Separate the number into its integer and fractional portions: the integer is 85 and the fraction is 0.4. Convert 0.4 to a fraction: 2/5. Combine the two: 85 2/5.

If you want to know how to do it on a particular calculator, please specify the make and model.

### What is the key to reduce fractions ?

The EL-501 doesn't display fractions. Some of Sharp's other calculators do, but not this one.

### How to find G.C.F. on a TI-30xIIs calculator?

I don't think there's specific key for this but you can do it this way:

1. Divide those 2 numbers for which you want to find gcf
2. If you get result as decimal number press keys [2nd][PRB] to display it as fraction
3. Also if fraction you get is in form a b/c (ex. 1 2/3) you have to convert it to form d/c (for 1 2/3 that would be 5/3)
4. Greatest common factor is then 1st number divided by numerator (or 2nd number divided by denominator)
For example:
• You want to find greatest common factor of 30 and 18.
• You divide them: you should get 5/3 (after converting result to fraction of form d/c, as described in steps 2 and 3).
• This means that 30/18=5/3=5x/3x (x is gcf here).
• Now you know that x=30/5=18/3=6 so greatest common factor is 6.

I hope this helps :)

### Formula for converting fractions into percentage.

Simplest method
1. divide the top of the fraction by the bottom
2. Then multiply the result by 100
3. add a percent sign to the answer so people know it is a percentage (i.e. per 100)
• e.g. 3/5 *100 = 0.6 * 100 = 60%

Alternative method Since percent means "per 100", you can try to convert the faction to the form ?/100
1. find a number that you can multiple the bottom of the fraction by to get 100
2. multiple both top and bottom of the fraction by that number
3. write down just the top number with the % sign added to the end
• e.g. 3/5 as a percentage
1. we can multiply 5 x 20 to get 100
2. multiple top and bottom by 20 = (3*20)/(5*20) = 60/100 = 60%

I hope this helps and good luck! If you have more questions - ask away! Please take the time to rate this answer.

### I don't know how to simplify fractions on this calculator.

You do not simplify fractions on the calculator. If the calculator is able to display fraction results, be sure that the form it gives you is the simplest. If the fraction is a mixed one there is usually a key to switch from mixed to improper, and from improper to mixed the keys are [a b/c] and [d/c]

### How do u do fractions

To do fractions on the TI-83, you must use parentheses.
The parentheses buttons (there are two of them, facing either way) are near the upper right corner of the buttons on the calculator.
To write a fraction, you must enclose it in parentheses, using the divide button (the slash) as the fraction sign (the line between the numerator and the denominator)
For example, this would be one half:
(1/2)
And this would be one third:
(1/3)
As long as the numbers are confined between parentheses, with no other numbers in there besides the fraction, they will act as a single group.
Don't ever be afraid to use plenty of parentheses, either!
For example, if you wanted to add one half to one third, and then multiply it all by three, the following would definitely be acceptable:
((1/2)+(1/3))*3

### I have a Casio fx-300ES calculator and everytime i push in a math problem it comes out as decimal form or fraction form. I don;t exactly know whats wrong with it, but it never gives me the right answer to...

I understand your frustration, but believe me there is nothing wrong with your calculator. You just have to invest a minimum amount of time to familiarize yourself with its powerful capabilities.
No matter. Your calculator has to input output modes. MathIO and LineIO. MthIO is new and it allows you to enter expressions as if you were doing it by hand (like in textbooks). LineIO is the old way.

In MthIO your displayed results are fractions or radicals (roots) or a mixture of the two. BUT if the screen cannot fit the fraction or radical form, the calculator will use decimal to display the result.

In LineIO you only have decimals results.

To get fraction or radical results configure the calculator to use MthIO. In this mode, if you want a result converted to decimal, just press the SD key. It will toggle between the two.

To set MthIO, press [SHIFT][MODE] and select [1:MthIO]
To set LineIO, press [SHIFT][MODE] and select [2:LineIO]

### I need to know how to do fraction on my TI-84 plus

Technically a fraction is just the ratio of two integers (division of two integers). To enter a fraction, type in the numerator, press the division key, then enter the denominator.

The problem is preventing the fraction from being evaluated. To do that press [MATH] key, select [1:

### How do you change decimals to fractions on a casio

If you enter an improper fraction or a mixed fraction with the the [a b/c] key it will be displayed as a fraction. This result being displayed you can press the [F-D] key to convert the fraction to decimal. If you do nothing else and you press the [F-D] key again, the original fraction will be restored.

However, it seems that you cannot enter an arbitrary decimal number and convert it to a fraction. The [F-D] key seems to work one way : from a fraction to a decimal number. You will only recover a fraction if the original number was a fraction.
