Matthew's small fish tank holds 12 liters. His large fish tank holds 25 liters. How many more liters does his large fish tank hold?

To determine how much volume has the large fish tank than that of the small fish tank, we simply get the ratio of the two volumes. We let V1 the volume of the large one and V2 for the smaller one. We do as follows:

V1 = kV2

25 = k (12)

k = 2.0833

Therefore, the larger tank is 2.0833 of the volume of the smaller tank.
