If Sally can paint 1 house in 4 hours, she can paint \"1%2F4\" of a house in 1 hour. Likewise, Jim can paint \"1%2F6\" of a house in 1 hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Together they can paint \"1%2F4%2B1%2F6\" house in 1 hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Complete the sum above and then take the reciprocal (invert the fraction) to get the time for both to complete the house together. Note -- your answer MUST be smaller than 4 hours. That's because Sally can do the job in 4 hours but now that Jim is helping, the job must go faster than that.\r
