Hello,
No the calculator cannot do that.
But if you do [2nd][Pi] [EXE] then just after [2nd][tan-1][2nd][Ans] you get 1. If you use the inverse trigonometric functions you will never have a value such as pi/4 or pi or pi/2. If angle unit is set to degrees you recover the exact values of the angles (they are integers anyway.
Hope it helps.

### 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 do i convert a degrees/minutes/second problem using the Casio Fx-115ES calculator? Can you provide an example? Thanks ZH

Use the key above the ENG key to enter a value in DMS form, ending each portion with the key. To convert it to decimal, press SD once (or twice if you get a fraction the first time).

Example: sine of 12 degrees 15 minutes:
sin 12 *** 15 *** =
where *** is the DMS key.
