So this particular repeating decimal corresponds to the fraction 1 / ( 10 " n " & minus; 1 ), where the denominator is the number written as " n " digits 9 . Knowing just that, a general repeating decimal can be expressed as a fraction without having to solve an equation.

Every terminating decimal representation can be written as a decimal fraction, a fraction whose divisor is a 0.999 & } } and 1.584999 & } } are two examples of this . ( This type of repeating decimal can be obtained by long division if one uses a modified form of the usual division algorithm .)

If you start with, " What is 32 / 7 you are going to get monsters like 4.571428571428 and unless that's what you want ( to demonstrate the repeating decimals of numbers divided by 7 ) it's a monster to deal with gradewise . talk ) 22 : 29, 20 October 2014 ( UTC)

It follows that any repeating decimal with period " n ", and " k " digits after the decimal point that do not belong to the repeating part, can be written as a ( not necessarily reduced ) fraction whose denominator is ( 10 " n " & minus; 1 ) 10 " k ".

For arithmetic, Bhrat + K [ c G a gives several algorithms for whole number multiplication and division, ( flag or straight ) division, fraction conversion to repeating decimal numbers, calculations with measures of mixed units, summation of a series, squares and square roots ( duplex method ), cubes and cube roots ( with expressions for a digit schedule ), and divisibility ( by osculation ).

A decimal may be a terminating decimal, which has a finite fractional part ( e . g . 15.600 ); a repeating decimal, which has an infinite ( non-terminating ) fractional part made up of a repeating sequence of digits ( e . g . 5.123 144 ); or an infinite decimal, which has a fractional part that neither terminates nor has an infinitely repeating pattern ( e . g . 3.14159265 . . . ).

I am basing this on the rule that, to convert a repeating decimal to a fraction, you just take only the group of numbers that repeats over a number of " 9's " equaling the number of numbers that repeats, i . e ., . 732732 . . . ( Repeating ) = 732 / 999 . And, if so, then what number comes right before . 9 ( Repeating ) in terms of size ? Preceding contribs ) 20 : 10, 8 November 2007 ( UTC)
