if you are 3/7 of the way and have 84 miles left to drive, how long is the entire length of the trip
\n" ); document.write( "let x=entire length of trip
\n" ); document.write( "3/7 of the total trip already completed, so this leaves 4/7 of the entire trip yet to be completed
\n" ); document.write( "(4/7)x=84
\n" ); document.write( "4x=7*84
\n" ); document.write( "x=7*21=147
\n" ); document.write( "entire length of trip=147 miles
\n" ); document.write( "
\n" );
