It is assumed that all the painters paint at the same rate
\n" ); document.write( "Their rate of painting for 4 painters is:
\n" ); document.write( "[ 1 house ] / [ 12 days ]
\n" ); document.write( "1 painter will paint at 1/4 of this rate, so
\n" ); document.write( "1 painter's rate = [ 1 house ] / 48 days ]
\n" ); document.write( "3 painters will paint at 3 times this rate, so
\n" ); document.write( "3 painter's rate = [ 3 houses ] / [ 48 days ]
\n" ); document.write( "[ 3 houses ] / [ 48 days ] = [ 1 house ] / [ 16 days ]
\n" ); document.write( "It will take 3 painters 16 days to paint the house
\n" ); document.write( "------------------------------------------------
