i believe this is a straight ratio.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ratio is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2 feet 3 inches divided by 1.5 pounds of water = 720 feet / x pounds of water.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2 feet 3 inches is equal to 2 + 3/12 = 2.25 feet.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ratio becomes 2.25 / 1.5 = 720 / x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cross multiply to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2.25 * x = 1.5 * 720\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 1.5 * 720 / 2.25 = 480 pounds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "there are 2000 pounds to a ton, so the displacement is 480 / 2000 = .24 tons.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
