You can put this solution on YOUR website! A drum of water is 3/7 full. When 28 ltrs are drawn from it. It is just 5/14 full.
Find the total capacity of the drum in ltrs.
:
Let x = total capacity of the drum
: x = x - 28
Multiply by 14 to clear the denominators, resulting in:
5x = 2(3x) - 14(28)
5x = 6x - 392
392 = 6x - 5x
x = 392
