Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

0.345 345 345 ... =345/999=115/333

Hi, Divide the top into the bottom number and you should get a decimal. 1/4 is .25 1/2 is .50 .....

To change the decimal in to to a fraction. Put the decimal over 100 and multiply.and then break that down.

To change from fraction to decimal, all it takes is a keypress. (change key)

.Not all decimal results (approximations) will be converted to fractions.

Anyway, if you want to set the calculator to display decimal results only,

Press SETUP

Press 2:EDITOR

Select 1:LINE.

Hi,

P12c display from Comma to Point This document describes how to change the display of the decimal point on the HP 12C (HP12C) Calculator from a comma (commas) back to a decimal point.

**Instructions**

Explanation The comma is the European equivalent of the decimal point.

This procedure is also applicable to HP12CP (Hewlett-Packard 12c Platinum) and HP12CPA (Hewlett-Packard 12c Platinum 25th Anniversary Edition).

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

To force a fraction to be displayed as a decimal number put a decimal mark at the end of the numerator OR the denominator. Fraction/decimal result is always decimal.

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

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
