Answer:

1980 litres :)

Explanation:

Since 4/15ths is 720 litres, you need to find the value of the other 11/15ths.

First, you can find the volume of the whole tank (15/15ths) by multiplying 720 by 15/4ths. (Any number multiplied by its reciprocal is one, so by multiplying 720, 4/15ths of the total volume, by 15/4ths, you get the total volume (1)).
720*(15/4)=2700 litres
But, you're not done yet. You found the total, now to find the remainder needed you find the difference. (15/15ths - 4/15ths = 11/15ths --> 2700 - 720 = 11/15ths --> 11/15ths = 1980 litres)
