Hint: First, we must understand that the weight is reduced to $\dfrac{1}{3}$ of its initial value, after the fish is dried. Hence, we need to divide the given weights of fresh fish, that is, 300 kg and 900 kg, to set the value of weight of dried fish for both cases.

We are given that when a fresh fish is dried, it loses $\dfrac{2}{3}$ of its weight and the final weight is $\dfrac{1}{3}$ of the weight of fresh fish.
So, if the weight of fresh fish is $x$ kg, then the weight of dried fish will be equal to $\dfrac{x}{3}$ kg.
Hence, using this information we can say that, if the weight of fresh fish is 300 kg, then the weight of dried fish will be equal to $\dfrac{300}{3}$ kg.
Again, using the same technique, we can say that if the weight of fresh fish is 900 kg, then the weight of dried fish will be equal to $\dfrac{900}{3}$ kg.
Note: We must understand that a multiplication by the fraction $\dfrac{1}{3}$, is exactly the same as division by 3. Also, we must note that the answer for the above question can also be in decimals or fraction, if the data is changed.
