Question about Casio Office Equipment & Supplies

Hi,

You are not specifying the brand and model number of your calculator and that makes things more difficult for me. On the Casio calculators (FX-300ES, FX-115ES, FX-991ES) there is key labeled [S to D] which toggles between Fractions/Radicals To Decimals.

On other calculators (Sharp), the key may be labeled F To E.

You should look for a key that has two letters with a two-sided arrow linking the letters.

Why I even try to answer a question that lacks basic information and give the opportunity to the asker to shoot me dead is beyond me.

Anyway, I hope it helps.

You should multiply the top line only of the fraction.

eg 2/3 x 5 = 10/3

This will often give an improper fraction, that is, one with the numerator (top line) greater than the bottom (denominator). Its value is then greater than one.

You can then reduce this by dividing the bottom into the top line, and writing the remainder as a fraction

eg 10/3 = 3 and 1/3

.

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.

Transforming 0.175 to fraction:

= 175/1,000

Reduce to lowest term (divide by 5 both the numerator and the denominator):

= 35/200

Reduce further by dividing both by 5:

= 7/40

This is the lowest terms now that it can't be reduced further.

The "Other" way round, Bottom number into ONE and multiply it by the Top. EG: 3/4 == 1 divided by 4 = 0.25, now we multiply, .25 by the Top number or in this case 3, that equals 0.75. 1/4 =0.25 x 3 = .75. 3/4 is the same as 0.75.

you want a line output

Shift > Mode > 2:LineIO or on the graphics one its sometimes 10:LineO etc.

look for something with line in it

Steve :P

you can also go press the 'mode' button, and go down until you're at 'Exact/Approx' and choose '3: Approximate'

Sep 10, 2008 | Texas Instruments TI-89 Calculator

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.
