Algebra.Com's Answer #82157 by Fombitz(32388)![]() ![]() You can put this solution on YOUR website! If you look at the sum as it starts to accumulate, you'll notice a pattern.\r \n" ); document.write( "\n" ); document.write( ".8 \n" ); document.write( ".88 \n" ); document.write( ".888 \n" ); document.write( ".8888 \n" ); document.write( ".88888 \n" ); document.write( ".888888 \n" ); document.write( ".8888888 \n" ); document.write( ".88888888\r \n" ); document.write( "\n" ); document.write( "Look for a fraction that has a repeating pattern. \n" ); document.write( "I know that 1/9=0.1111111.... \n" ); document.write( "So my sum looks like 8 times that much or 8/9. \n" ); document.write( " |
