just divide 3 by 2 and it gives you 1.5 which is the answer

Finding the remainder from a division calculation is often referred to as using the MOD function, though this isn't available directly on the fx-991ES.

To obtain the remainder, for example when dividing 10 by 7, you can only divide 7 into 10 once, leaving a remainder of 3.

For larger numbers, eg when dividing 389487 by 31 (equivalent to 389487MOD31) the division gives an answer of 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD or remainder calculation involving integers has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculator's working capacity.

An alternative method which avoids the rounding of the fractional part is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

Loook for a key marked F<>D and press it to toggle between fraction and decimal displays.

There are two options.

1) Whenever you want the answer in decimal form, place a decimal after at least one of the numbers.

For example: instead of using (1/2) use (1/2.)

2) Press the "Mode" button. Scroll down the list that appears until you find "Exact/Approx". If you set it to "Approximate", then it will always give the answer in decimal form. If you set it to "Exact", it will give the answer in fraction form.

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.

Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer

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

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

To do fractions, just use the normal divide button.

To see the exact answer, hit MODE and scroll down to Exact/Approx and change to EXACT. In this mode, it will give the fraction always unless you press the special (green button with diamond) before pressing ENTER and it will give the approximate decimal value.

Go into MODE to the second page. In Exact/Approximate, change it to Approx instead of Auto or Exact. This will give you decimals instead of fractions.
