You can put this solution on YOUR website!
Let \"a\" = number of sailors
\n" ); document.write( "Let \"b\" = number of soldiers
\n" ); document.write( "Right away, you know there are
\n" ); document.write( "less sailors than soldiers, since \"4%2F5\"
\n" ); document.write( "is smaller than \"1\"
\n" ); document.write( "Suppose you could actually have \"4%2F5\" of a
\n" ); document.write( "sailor? Then \"%284%2F5%29%2F1+=+a%2Fb\" would be true
\n" ); document.write( "The problem says \"a+%2B+b+=+27\"
\n" ); document.write( "If \"a%2Fb+=+12%2F15\", then
\n" ); document.write( "\"12+=+%284%2F5%29%2A15\" and also
\n" ); document.write( "\"12+%2B+15+=+27\"
\n" ); document.write( "
\n" );
