Hello,
To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.
Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.

Hello,
Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.
To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.
Thus [SHIFT][MODE][1:MathIO].
Hope it helps.

Hello,
Since you bent on deactivating the very features that make your calculator so versatile and so powerful, here it is.
Press [SHIFT][MODE][2:LineIO] and you will see no more fractions, nor radicals etc. You asked for it.
Hope it helps.

Testimonial: "I bought the calculator because it was on sale and I like Casio calculators; not for its fractional abilities. I can easily switch it back now. Thanks"

SOURCE: Why does it solve in fractions?

The calculator has two Input/Output modes: the default MthIO (new) and the old LineIO.

1. In MthIO you enter fractions and radicals as you see them in textbook (multiple levels). Calculations are exact and results are generally a mixture of fractions and radicals.
2. In LineIO, numbers are entered the old way and all numbers, operations are written on a single line. All fractions and radicals are converted into decimals numbers.
   

If you use the default MthIO you can let your calculator perform the operations in exact arithmetic. When you obtain the end result, you can easily convert a fraction/radical result into a decimal one by pressing the [S<=>D] key, or press [SHIFT][=] instead of [=].

However if you do not care about the MthIO and its nifty functionalities, you can configure your calculator to use LineIO.

To set LineIO press [SHIFT][MODE][2:LineIO]
