right now we are at 1/8 full
\n" ); document.write( "15 gallons got us up to 3/4 = 6/8.
\n" ); document.write( "This means 15 gallons is the same as 5/8 tank.
\n" ); document.write( "We can create a proportion to get our answer as
\n" ); document.write( " $\"15%2F%285%2F8%29+=+G%2F1\"$
\n" ); document.write( "step 1 - cross multiply to get
\n" ); document.write( " $\"15+=+%285%2F8%29G\"$
\n" ); document.write( "step 2 - multiply 15 by (8/5) to get
\n" ); document.write( " $\"24+=+G\"$
\n" ); document.write( "So, 24 - 15 = 9 gallons to fill the tank. \n" ); document.write( "

\n" );
