Answer 2

Understanding the Division of the Salmon

When you bought a 2kg salmon from the store, you ended up with 1.2kg of fillet and discarded the rest. Let's calculate the parts of the whole fish that were used for the fillet and the part that was discarded.

Calculation

To find out what part of the whole fish was used for the fillet and what part was discarded, we can use the following calculation:

1. Part Used for Fillet: - Weight of the fillet = 1.2kg - Weight of the whole fish = 2kg - Part used for fillet = (Weight of the fillet / Weight of the whole fish) * 100%

Using the above calculation, we can find the percentage of the whole fish used for the fillet.

2. Part Discarded: - Weight of the discarded part = Weight of the whole fish - Weight of the fillet

By subtracting the weight of the fillet from the weight of the whole fish, we can determine the weight of the discarded part.

Results

Using the above calculations, we find that: - Part Used for Fillet: 60% of the whole fish was used for the fillet. - Part Discarded: 40% of the whole fish was discarded.

Conclusion

So, you used 60% of the whole fish for the fillet and discarded 40% of it.
