You can put this solution on YOUR website!
4*(1/2) is 2
\n" ); document.write( "7*(9/10) is 63/10 which is 6.3
\n" ); document.write( "2*(1/7)=2/7 which is (now estimating) a bit less than (1/6).
\n" ); document.write( "5*(7/8)=35/8 which is a bit more than 4. Since 35 is a bit more than 32 and (32/8)=4.\r
\n" ); document.write( "\n" ); document.write( "So if we add this all up we get (about) 2+6.3+4+.2=12.5 (or therabouts)
\n" ); document.write( "
\n" );
