\n" ); document.write( " $\"75\"$ % of a number $\"x\"$ is $\"120\"$ :\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"75\"$ % = $\"75%2F100=0.75\"$ \r
\n" ); document.write( "\n" ); document.write( "so, $\"0.75x=120\"$ ....solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=120%2F0.75\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=160\"$ ........the number is $\"160\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and now we can find $\"40\"$ % of the number $\"160\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"40\"$ %= $\"40%2F100=0.40\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0.40%2A160=x\"$ ....solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=160%2A0.40\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=64\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
