Set up a ratio.
\n" ); document.write( "Percent means out of 100.
\n" ); document.write( "5 is to X as 10 is to 100 (10/100=10%).
\n" ); document.write( " $\"5%2FX=10%2F100\"$
\n" ); document.write( " $\"X=500%2F10=50\"$
\n" ); document.write( "5 out of 50 is 10%.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Since it's less that 100%, it has to be less than 1.
\n" ); document.write( "So 4 1/6 can't be right.
\n" ); document.write( "Again, percent means out of 100.
\n" ); document.write( " $\"18%2F100=%282%2A9%29%2F%282%2A50%29=%28cross%282%29%2A9%29%2F%28cross%282%29%2A50%29=9%2F50\"$

\n" );
