\n" ); document.write( "Let's say we had a tank that was 30 gallons in total capacity.
\n" ); document.write( "I'm picking on 30 because it is the LCD of the fractions 1/10 and 2/3
\n" ); document.write( "Note: 1/10 = 0.10 = 10%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If the tank is 2/3 full, then (2/3)*30 = 20 gallons of gas is in the tank
\n" ); document.write( "Then 10% of that amount (20 gallons) is taken out, meaning we take out 0.10*20 = 2 gallons of gas. We then have 20-2 = 18 gallons left.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The amount of empty space is 30-18 = 12 gallons\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The fraction of empty space is 12/30 = (6*2)/(6*5) = 2/5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 2/5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The tutor @josgarithmetic has the right idea, but somehow got the 2/5 and 3/5 mixed up I think.
\n" ); document.write( " \n" ); document.write( "
