Try this:
\n" ); document.write( "Cubes to (cubes+spheres) = 16 to 25. Let x = number of cubes in 225 cubes plus spheres.
\n" ); document.write( " $\"16%2F25+=+x%2F225\"$ Solve for x.
\n" ); document.write( " $\"16%28225%29%2F25+=+x\"$
\n" ); document.write( " $\"x+=+144\"$
\n" ); document.write( "There are 144 cubes in the box.
\n" ); document.write( "Check:
\n" ); document.write( " $\"16%2F9+=+144%2F81\"$ Divide the numerator and denominator of the second fraction by 9.
\n" ); document.write( " $\"16%2F9+=+16%2F9\"$ \n" ); document.write( "

\n" );
