m/r = (1 inch * (1/12) ft/inch ) / (5.4 ft)
\n" ); document.write( "m/r = (1/12 ft) / (5.4 ft)
\n" ); document.write( "---
\n" ); document.write( "m/r = (1/12 ft) / (5.4 ft)
\n" ); document.write( "m/13.5 = (1/12 ft) / (5.4 ft)
\n" ); document.write( "m = (13.5 ft)(1/12 ft) / (5.4 ft)
\n" ); document.write( "m = (13.5)(1/12)/(5.4)
\n" ); document.write( "m = 0.2083333 ft
\n" ); document.write( "m = (0.2083333 ft)*(12 inch/ft)
\n" ); document.write( "m = 2.5 in
\n" ); document.write( "---
