40-50% of fish are sold each year
salmon
They caught and sold fish, just like today.
Y caught 6 fish. X caught 30 fish (5x6). Together they caught 36 fish.
If x caught 5 times as many fish as y, then there were 6 groups of the same number of fish caught, and each group would have been 6 fish if there were 36 fish all together. x must have caught 30 (6 x 5) fish, leaving just 6 for y to have caught.
Many varieties of fish are caught in the Baltic Sea

Fish can be found in all oceans, most lakes and rivers. They are caught by different countries, and then shipped to processing plants where they take out the unwanted garbage. Unfortunately many species of fish are overfished and are decreasing in number. After it is processed, it is sold to different countries where it is eaten. Hope this helps!
