It took 7 3/4 gallons of gas to fill the tank of the family car.
\n" ); document.write( "If the tank was 1/8 full when they arrived at the gas station how much gas does the tank hold?
\n" ); document.write( ":
\n" ); document.write( "Change 7 $\"3%2F4\"$ to $\"31%2F4\"$ gal
\n" ); document.write( ":
\n" ); document.write( "Let x = no. of gallons the tank can hold
\n" ); document.write( ":
\n" ); document.write( "x = $\"1%2F8\"$ x + $\"31%2F4\"$
\n" ); document.write( "Multiply by 8, results
\n" ); document.write( "8x = x + 2(31)
\n" ); document.write( "8x - x = 62
\n" ); document.write( "7x = 62
\n" ); document.write( "x = $\"62%2F7\"$
\n" ); document.write( "x = 8.857 gal, the tank will hold
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "see if that is true using a calc,
\n" ); document.write( " enter $\"1%2F8\"$ *8.857 + $\"31%2F4\"$ results: 8.857 \n" ); document.write( "

\n" );
