Algebra.Com's Answer #685325 by jorel1380(3719)![]() ![]() You can put this solution on YOUR website! If Michael's crew can build a house in 8 days, then they finish 1/8th of a house per day. Similarly, John's crew finishes 1/10th of a house per day. Working together, they can finish: \n" ); document.write( "1/8 + 1/10=5/40 + 4/40, or 9/40ths of a house per day. Therefore, 1 house takes 1/(9/40), or 40/9, or 4-4/9ths days. ☺☺☺☺ \n" ); document.write( " |
