In order for 1/6 of the female residents
\n" ); document.write( "to marry 1/4 of the males, then 1/6 of the
\n" ); document.write( "female residents has to equal 1/4 of the males
\n" ); document.write( "because marriage is a one-to-one match.
\n" ); document.write( "\"%281%2F6%29%2Af+=+%281%2F4%29%2Am\"
\n" ); document.write( "Multiply both sides by \"12\"
\n" ); document.write( "(1) \"2f+=+3m\"
\n" ); document.write( "Also, I am given:
\n" ); document.write( "(2) \"f+%2B+m+=+8000\"
\n" ); document.write( "I can say this because all the residents
\n" ); document.write( "are either male or female
\n" ); document.write( "From (2),
\n" ); document.write( "\"m+=+8000+-+f\"
\n" ); document.write( "Substitute this in (1)
\n" ); document.write( "\"2f+=+3%2A%288000+-+f%29\"
\n" ); document.write( "\"2f+=+24000+-+3f\"
\n" ); document.write( "\"5f+=+24000\"
\n" ); document.write( "\"f+=+4800\"
\n" ); document.write( "and, from (2)
\n" ); document.write( "\"4800+%2B+m+=+8000\"
\n" ); document.write( "\"m+=+3200\"
\n" ); document.write( "There are 4800 female residents and 3200 male residents
\n" ); document.write( "check:
\n" ); document.write( "\"%281%2F6%29%2Af+=+%281%2F4%29%2Am\"
\n" ); document.write( "\"%281%2F6%29%2A4800+=+%281%2F4%29%2A3200\"
\n" ); document.write( "Multiply both sides by \"12%2F100\"
\n" ); document.write( "\"2%2A48+=+3%2A32\"
\n" ); document.write( "\"96+=+96\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
