1 painter does 1/40 house per hour
\n" ); document.write( "The other does 1/35 per hour
\n" ); document.write( "Together they do 1/40 + 1/35 house per hour
\n" ); document.write( "= (35+40)/35*40 = 75/1400 = 3/56
\n" ); document.write( "3/56 houses per hour --> 56/3 hours/house
\n" ); document.write( "--------------------
