Question about Sharp EL-520WBBK Calculator

When I do Trig I have a numerical decimal form as an answer.How to I transpose it to a fraction.

Enter in the equation, or what you need to solve. Press the equals button, and if your answer appears as a decimal, hit the button above the number '8'. It says something like 'a b/c'. Your number should now appear in fraction form. To get it as an improper fraction, simply hit the '2ndF' button and then hit the 'a b/c' button again.

Enjoy :)

The TI-83 can only convert a decimal to a fraction if the denominator has no more than three digits.

Try . 5 MATH FRAC

Does that give you 1/2?

Not quite true for OS 2.56 MP for the TINspire with Ti84 keyboard. To convert a complex decimal value, that you just calculated, into a fraction use the command Math [1:>Frac] and it will convert the value to complex fractions

See below.

If the calculator give you an answer in fractional or symbolic form, you can convert it to numerical form by pressing diamond then ENTER.

To have all answers come out in numerical form, press MODE F2 then down-arrow to the "Exact/Approx" line, right-arrow, select either AUTO or APPROXIMATE, then press ENTER twice.

A fraction is in fact a ratio of two number: a division of a numerator by a denominator. The key used for the division operation is the one above the multiplication sign and below the caret [^], and in thee rightmost column of keys.

Beware that this calculator converts any ratio of two numbers into a decimal value. To keep a fraction in a fraction form you must use the [|=>Frac] or [ToFrac] command. To convert a decimal result to a fraction, use the [|=>Dec] command.

These commands are accessible through the CATALOG or more easily by pressing [MATH] (under the ALPHA key) and selecting [1:|=>Frac], or [2:|=>Dec]

Ex: to keep 27/48 in fraction form you enter

27 [/] 48 [MATH][1:|=>Frac] [ENTER]. Result is 9/16

You will notice that the resulting fraction is reduced to its simplest form.

To convert the above result from fraction to decimal press [MATH][2:|=>Dec]

A fraction can always be approximated by a decimal value but the converse is not always possible.

You can convert between Standard Form (with fractions and pi) or
Decimal form by using the "S<->D" button. Use Mode 1 if you
mostly prefer fraction answers and you can use the SD button to convert
to decimal or use Mode 2 if you mostly prefer decimal answers and use
the SD button to see the fraction.

I hope this helps and good luck!

Place both the base and the exponent in parentheses

(3/4)^(-2) then press enter. Your answer will be in decimal form at first 1.777...

Press MATH

Select the 1: Fraction option and it will convert your decimal value to the fraction answer of 16/9.

Negative exponents flip the fraction. For instance, (3/4)^(-1) = 4/3. So for (3/4)^(-2) you could just square the numerator and denominator separately to get 9/16, and then flip the fraction to account for the negative. That will give you 16/9.
