Calculating the Amount of Fresh Fish Needed to Get 231 kg of Dried Fish

To calculate the amount of fresh fish needed to obtain 231 kg of dried fish when the dried fish constitutes 55% of the mass of the fresh fish, we can use the following formula:

Amount of fresh fish = (Amount of dried fish) / (Percentage of dried fish as a decimal)

Using this formula, we can calculate the amount of fresh fish needed.

Calculation

The percentage of dried fish as a decimal is 55% or 0.55.

Amount of fresh fish = 231 / 0.55

Amount of fresh fish ≈ 420 kg

Therefore, approximately 420 kg of fresh fish is needed to obtain 231 kg of dried fish.

This calculation is based on the given percentage of dried fish as a fraction of the mass of the fresh fish
