Question

Afish tank can hold 45 litres of water when filled to the
brim. It is 3/5 filled. It 1/3 of water is removed, how much
more water must be added in order to fill the tank to the brim?​

Answer 1

Answer:

27 l

Step-by-step explanation:

Total capacity = 45 l

Quantity filled = 3/5 of 45 = (3*45)/5 = 27 l

Total water removed = 1/3 of 27 = 27/3 = 9 l

Total water left = 27 - 9 = 18 l

Amount required to fil the tank = 45 - 18 = 27 l
