Decimal mode casio

Your problem is not with the scientific display, rather it is with decimal representation (approximate) or fraction/radical (exact). representation.
If your results are in fraction/radical form press the [S<>D] key to switch from one to the other.
The calculator is by default in the MATHIO t output mode: results are in fraction/radical form.
If you don't like to work with this mode just change the IO mode to LineIO. To do so, press [SHIFT][Mode](Setup) and selct 2:LineIO

You want to change the display mode. Press SHIFT MODE. Then press 6 and a number specifying the number of digits after the decimal point for fixed decimal notation, or 6 and 1 or 2 to specify one of the floating point modes.

While using Casio fx-300ES , I am unable to get answers in decimals. For eg. 3/10...should give 0.3, but the answer is again displayed as 3/10. any way to solve this issue?

The calculator has two Input/Output modes: MathIO and LineIO.

LineIO is the old way of entering numbers in calculators and results are always displayed as decimal numbers. Some calculators have a fraction feature and would convert a fraction to a decimal number and back.

In MathIO you enter expressions as you would by hand or as you see them written in textbooks.
In this mode, results are by default displayed as fraction or fractions/ radicals.
To convert the fraction/radical to decimals you just press the [SD] key. If you press again you cycle through all the available display formats.
So you can (if you want) use the MathIO to manipulate expressions and convert only the last result to decimal. By the way, fractions and radicals are generally more accurate than their decimal representations.

If however seeing fractions and radicals is too painful, just set the LineIO as your default mode. To do so press [SHIFT][MODE] to open (SETUP), then select [2:LineIO]

How do you make it so the answer is decimals not fractions

If you do not want to see fractions and radicals anymore just set the calculator input output (I/O) mode to lineIO:
Press [SHIFT][MODE](SETUP) and select [2:LineIO].

If, however, you appreciate the functionalities of the MathIO that allow you to manipulate fractions, radicals, and other nifty things you could not do before, but just want your final results to be in decimal fornat that can be arranged too.
Here is how
  1. Set the I/O mode to MtahIO: Press [SHIFT][MODE][1:MthIO]
  2. Enter your expressions, and when you are finished press [SHIFT][=]. Your result will be in decimal fornat.
  3. Alternatively, you can calculate your result in MthIO and convert the fractions/radicals to decimals by pressing the [S<=>D] key, the one located between the [)] and the [M+] keys.
  4. Every time you press that key you toggle the display from fractions/radicals to decimal and back.

When I divide answers are always given in Fractions. Can I change it to come out in decimals?

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
