Katherine drove 100 miles on 7 gallons of gasoline. How far can she drive on a full tank of 20 gallons?
\n" ); document.write( ".
\n" ); document.write( "From:\"Katherine drove 100 miles on 7 gallons of gasoline.\" we get the following proportion:
\n" ); document.write( "100/7
\n" ); document.write( ".
\n" ); document.write( "Because we would like to consider how far 20 gallons will go instead of 7 we have our equation of:
\n" ); document.write( "If x = distance traveled on 20 gals of gas
\n" ); document.write( "100/7 = x/20
\n" ); document.write( "(100/7)20 = x
\n" ); document.write( "285.714 miles = x
\n" ); document.write( "
\n" );
