\n" ); document.write( "\n" ); document.write( "I solved it like this: 17x72=1224 in., then I converted inches to feet by dividing by 12 as such 1224/12 = 102 ft. Did I work the problem correctly?

Use proportion comparing ON PAPER to REAL LIVE VALUE.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1%2F72=17%2FR=onpaper%2Freallivevalue\". The variable R is for the real live value of the wing span. Solve for R.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"R%281%2F72%29=%2817%2FR%29R\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"R%2F72=17\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"R=17%2A72\"-----unit of INCHES.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can simply use one more proportion if you want FEET instead of just INCHES.
\n" ); document.write( "you KNOW 12 inches is 1 foot.
\n" ); document.write( "\"%2817%2A72%29%2F%28F%29=12%2F1\", using F for the amount of feet; solve for F.
