Algebra.Com's Answer #586527 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! You can say: \n" ); document.write( "5 bricklayers take 6 days to do 1 job \n" ); document.write( "----------------------------------- \n" ); document.write( "If another job requires 4 times the number of bricks \n" ); document.write( "you can say that is 4 jobs, so \n" ); document.write( "7 bricklayers take \n" ); document.write( "------------------------------------------ \n" ); document.write( "7 times as many bricklayers can do 1 job in 1/7 the time, so \n" ); document.write( "35 bricklayers take 6/7 days to do 1 job \n" ); document.write( "----------------------------------------- \n" ); document.write( "1/5 as many bricklayers will take 5 times as long, so \n" ); document.write( "7 bricklayers take 30/7 days to do 1 job \n" ); document.write( "-------------------------------------- \n" ); document.write( "4 jobs will take 4 times as long, so \n" ); document.write( "7 bricklayers take 120/7 days to do 4 jobs \n" ); document.write( "------------------------------------- \n" ); document.write( " \n" ); document.write( "7 bricklayers take 17 and 1/7 days to do 4 jobs \n" ); document.write( "------------------ \n" ); document.write( "Hope I got it\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
