Based on the data provided in the table and the results calculated:
1. To find the difference in deaths:
Western Europe: 35.5 million (in 1340) - 22.5 million (in 1450) = 13.0 million deaths.
Eastern Europe: 13 million (in 1340) - 9.3 million (in 1450) = 3.7 million deaths.
Thus, the number of deaths in Western Europe (13.0 million) was greater than the number of deaths in Eastern Europe (3.7 million).
2. To find the percentage change:
Western Europe: [tex]\(\frac{13.0}{35.5} \times 100 \approx 36.62\%\)[/tex]
Eastern Europe: [tex]\(\frac{3.7}{13} \times 100 \approx 28.46\%\)[/tex]
Comparing these percentages, the difference in percentage change is significant, indicating that the percentage change in population was not about the same in both regions.
Thus, the complete sentences should be:
This period saw more deaths in western Europe than in eastern Europe.
The percentage change during this period was not about rabout he same.
