Write 1.666... as an equivalent fraction in its lowest terms.
\n" ); document.write( "Well, the good news is that a repeating decimal (such as 1.666...) is a rational number and can, therefore, be expressed as the ratio of two integers (i.e. a fraction)...but, expressing a repeating decimal as a fraction requires a little more work than does converting a terminating decimal.
\n" ); document.write( "Here's how it goes:
\n" ); document.write( "First, separate the integer from the decimal so that we can convert just the decimal part (0.666...) to its equaivalent fraction.
\n" ); document.write( "Let n = 0.666... Multiply both sides by 10
\n" ); document.write( "10n = 6.666... Now subtract n from 10n
\n" ); document.write( "10n-n = (6.666...) - (0.666...)
\n" ); document.write( "9n = 6 Divide both sides by 9
\n" ); document.write( "n = 6/9 ...but n = 0.666..., so
\n" ); document.write( "0.666... = 6/9 Reduce this to:
\n" ); document.write( "0.666... = 2/3
\n" ); document.write( "Finally, add the integer back to get:
\n" ); document.write( "1.666... = 1 2/3 or, if you need it as a improper fraction, then:
\n" ); document.write( "1.666... = 5/3\r
\n" ); document.write( "\n" ); document.write( "You can check this with your calculator by dividing 5 by 3 and the calculator will display 1.666...
\n" ); document.write( " \n" ); document.write( "
\n" );
