You can put this solution on YOUR website!
if he uses 3 cans per day and he has 27 cans
\n" ); document.write( ":
\n" ); document.write( "27/3 should give us the amount of days it will last
\n" ); document.write( ":
\n" ); document.write( "9 days
\n" ); document.write( ":
\n" ); document.write( "27 cans/ 3 (cans/day) thats cans/(cans/day)..invert (cans/day) and multiply
\n" ); document.write( ":
\n" ); document.write( "27/3=9 $\"cross%28%28cans%29%29%2A%28day%2Fcross%28cans%29%29=%28days%29\"$ most of the time when you just look at the units you can figure a problem out \n" ); document.write( "
