You can put this solution on YOUR website!
Saturday she used 2/5th. So how much was left for Sunday?
1+-+%282%2F5%29 = 3%2F5
Sunday she used 3/4 of what was left. That will leave her with 1/4 of what she started Sunday .
%281%2F4%29+%2A+%283%2F5%29+ = 3%2F20 of a tank is left for Monday. Dad won;t be happy
