You can put this solution on YOUR website!
This can be solved as a proportion:\r
\n" ); document.write( "\n" ); document.write( "\"%28143.4%2Fx%29=%286%2F72%29\"\r
\n" ); document.write( "\n" ); document.write( "Next cross-multiply:\r
\n" ); document.write( "\n" ); document.write( "\"%28143.4%2A72%29=%286%2Ax%29\"\r
\n" ); document.write( "\n" ); document.write( "This simplifies to \"10324.8=6x\"\r
\n" ); document.write( "\n" ); document.write( "Now divide both sides by 6 to get:\r
\n" ); document.write( "\n" ); document.write( "\"1720.8=x\"\r
\n" ); document.write( "\n" ); document.write( "This car can travel 1720.8 miles on 72 gallons of gasoline.\r
\n" ); document.write( "\n" ); document.write( "Also, you could have reduced the \"6%2F72\" to \"1%2F12\" and solve it normally if you would have liked to.\r
\n" ); document.write( "\n" ); document.write( "Hope this Helps!
