Set Up a ratio:
\n" ); document.write( "[ gallons ] / [ gallons ] = [ tbspns ] / [ tbspns ]
\n" ); document.write( " $\"+20+%2F+50+=+3+%2F+x+\"$
\n" ); document.write( " $\"+2+%2F+5+=+3+%2F+x+\"$
\n" ); document.write( " $\"+2x+=+3%2A5+\"$
\n" ); document.write( " $\"+2x+=+15+\"$
\n" ); document.write( " $\"+x+=+7.5+\"$
\n" ); document.write( "She should add 7.5 tablespoons to her new aquarium \n" ); document.write( "

\n" );
