- Page 2 The HP 9g has three keys to handle fractions, namely O, ~o and ~n . The symbol used by the HP 9g to show a fraction (i.e. the equivalent to the symbol “/”, sometimes called solidus) is “ ” and is entered into the entry line by pressing O.
- Page 3 The entry line now reads 3 9. Press = to display the result line. The fraction now displayed is 1 3, which is equivalent to the entered fraction but reduced to its simple form. The HP 9g always tries to find the simplest equivalent fraction.
- Page 4 No cancellation is possible this time, so the result is –1 57 125. Note that the third number is not actually a mixed number strictly speaking because its fraction part is not proper. Nevertheless, your HP 9g can handle it as well and will return the reduced, proper form. Press: 3O19O5= which returns the mixed number Fractions can be entered and displayed wherever ordinary decimal numbers can be used.
- Page 5 = c/d then ad = bc. Doing the division is another way. But let your HP 9g do the hard part, and just enter both fractions. Since the Hp 9g carries out an automatic simplification, if the fractions displayed in the result line are the same then they are equivalent.
- Page 6 π is calculated to 24 significant digits. Too many digits for F↔D to handle. (Also, bear in mind that denominators on the HP 9g must be less than 10000). π has to be rounded to four decimal places before attempting the conversion.
