You can put this solution on YOUR website!
I recommend that you convert the inches to feet, and work the problem in decimal format. You have a calculator don't you? \r
\n" ); document.write( "\n" ); document.write( "5 inches = 5/12 = .416666 feet
\n" ); document.write( "3 inches = 3/12 = .25 feet\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply 8.41666666*5.25, etc.\r
