You can put this solution on YOUR website!
so in one hour she can do 8/4=2 sections
\n" ); document.write( "and does 2/8= 1/4 in one hr
\n" ); document.write( "and brother can do 8/5=1 3/5=1.6 sections in one hr
\n" ); document.write( "1.6/8=1/5 of the job in one hr.\r
\n" ); document.write( "\n" ); document.write( "x/4+x/5=1
\n" ); document.write( "5x+4x=20
\n" ); document.write( "9x=20
\n" ); document.write( "x=20/9
\n" ); document.write( "x=2 2/9 hrs
\n" ); document.write( "if nat works two hrs alone then she has done half the job\r
\n" ); document.write( "\n" ); document.write( "which leaves 4 sections to do or 1/2 the job to do
\n" ); document.write( "x/4+x/5=1/2
\n" ); document.write( "9x=10
\n" ); document.write( "x=1 1/9 hrs.
\n" ); document.write( "so nat worked 2+1 1/9=3 1/9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
