Algebra.Com's Answer #262687 by neatmath(302)![]() ![]() You can put this solution on YOUR website! We have the repeating number 0.123123123123... \r \n" ); document.write( "\n" ); document.write( "Let n be our number. \r \n" ); document.write( "\n" ); document.write( "n=0.123123123... \r \n" ); document.write( "\n" ); document.write( "1000n=123.123123123... \r \n" ); document.write( "\n" ); document.write( "And then we can subtract the first number from the second number to \"cancel\" out the repeating decimals! \r \n" ); document.write( "\n" ); document.write( "We would end up with \r \n" ); document.write( "\n" ); document.write( "999n=123 \r \n" ); document.write( "\n" ); document.write( "Then just solve for n! \r \n" ); document.write( "\n" ); document.write( "n=123/999 or simplifying the fraction, we have: \r \n" ); document.write( "\n" ); document.write( "n=41/333 \r \n" ); document.write( "\n" ); document.write( "I hope this helps! \n" ); document.write( " |
