Let $\"+x+\"$ = 100% of the population
\n" ); document.write( "Between the 2 ages is:
\n" ); document.write( " $\"+.55x+-+.25x+=+.3x+\"$
\n" ); document.write( "----------------------
\n" ); document.write( "If 55% is over $\"+40+\"$ , then 45%
\n" ); document.write( "must be under $\"+40+\"$
\n" ); document.write( "-----------------------
\n" ); document.write( "( between the 2 ages ) / ( less the 40 ) = $\"+.3x+%2F+.45x+\"$
\n" ); document.write( " $\"+.3x+%2F+.45x+=+3%2F45+\"$
\n" ); document.write( " $\"+3%2F45+=+1%2F15+\"$
\n" ); document.write( " \n" ); document.write( "
