Problema Solution

Steven poured 8 gallons of water into his aquarium.

4/5 of the aquarium was filled.

How many gallons of water does the aquarium hold altogether?

Answer provided by our tutors

let total capacity = x gallons

when poured 8 gallons, capacity became (4/5)*x gallons

therefore,

(4/5)*x = 8

ie x = 10 gallons.
