you can also go press the 'mode' button, and go down until you're at 'Exact/Approx' and choose '3: Approximate'

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button
2) Press the "MODE/SETUP" button
3) Press the "2" button
This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal

Are you using a ti-89? If so, check your mode settings and change Exact to Approximate.

This function is FIX or FSE near the dot [.] or above it, so press [2nd] the the [FIX] where it located button [.] for example then the dot [.] him self: [2nd] [FIX] [.]
Rate me, thanks.

### How to divide fractions using calculators?

To divide fractions proceed as you usually do with any number. Just make sure to enclose each fraction in parentheses. You may want to remember a simple rule: To divide a fraction by another, multiply the first one by the reciprocal of the other:

### How do I change a percentage to a fraction

### How to convert percent to fraction

1. Divide the percent by 100 to get decimal number.
2. 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.
3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
Example:
f = 10 power 2 = 100
4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
Example:
2.56 * 100 / 100 = 256 / 100
5. Find the greatest common divisor (gcd) of the fraction. Example:
gcd(256,100) = 4
6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
256 / 100 = (256/4) / (100/4) = 64/25
Example 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

### How to divide mixed numbers?

Probably the simplest is to convert both numbers to improper fractions then divide.
Some calculators can work with fractions. With one of those, simply enter the first mixed number, then divide by the other.

### 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 :)

### My TI-30XIIS calculator displays an arrow,an DEG, and a K always on my screen whenever i try to do simple multiplication. it says Syntax error and will not compute an answer.............

I had this problem also and just fixed it. I hit 2nd key...don't hold it, (it should say 2nd in the lower left corner across from the DEG) then click the K button (also the divide key). The arrow and DEG will remain, but do not affect simple math calculations. Hope this helps!

When you get a fraction for he answer: shift-S<->D[a b/c<->d/c]

This way, you change it to a mixed fraction or improper fraction
