To calculate the percentage of illegal fishing in one year, you can follow these steps:
1. **Determine the legal catch limit:**
The legal catch limit for tuna is 30,000 tons per year.
2. **Calculate the excess catch:**
The difference between the true quantity caught and the legal limit is 48,000 tons - 30,000 tons = 18,000 tons.
3. **Calculate the percentage of illegal fishing:**
To find the percentage of illegal fishing, divide the excess catch by the legal catch limit and then multiply by 100 to get the percentage.
Percentage of illegal fishing = (Excess catch / Legal catch limit) * 100
Percentage of illegal fishing = (18,000 tons / 30,000 tons) * 100
Percentage of illegal fishing = 0.6 * 100
Percentage of illegal fishing = 60%
Therefore, the percentage of illegal fishing in one year is 60%. This means that 60% of the tuna caught exceeds the legal limit set to address the global fish crisis.
