$\"+1%2F160+=+x%2F45+\"$
\n" ); document.write( "Multiply both sides by $\"+45+\"$
\n" ); document.write( " $\"+x+=+45%2F160+\"$
\n" ); document.write( " $\"+x+=+.28125+\"$ feet
\n" ); document.write( " $\"+.28125+%2A+12+=+3.375+\"$
\n" ); document.write( "The length of the model engine is 3 and 3/8 inches \n" ); document.write( "
