Final answer:
To calculate the percentage of deaths that occurred after 2009, divide the number of deaths that occurred after 2009 by the total number of deaths and multiply by 100.
Step-by-step explanation:
To calculate the percentage of deaths that occurred after 2009 (from 2010 onwards), we need to divide the number of deaths that occurred after 2009 by the total number of deaths, and then multiply by 100 to get the percentage.
For example, if there were 5000 deaths in total and 3000 deaths occurred after 2009, we would calculate:
Percentage = (3000 / 5000) * 100 = 60%.
Therefore, to find the percentage of deaths that occurred after 2009, you would need to know the total number of deaths and the number of deaths that occurred after 2009.
