A national health campaign aims to vaccinate 80% of the population. If the population is 5 million, how many people need to be vaccinated?

Step 1: Identify the total population, which is 5 million.
Step 2: Convert 5 million into a numerical format, which is 5,000,000.
Step 3: Determine the percentage of the population that needs to be vaccinated, which is 80%.
Step 4: Convert 80% into a decimal format, which is 0.80.
Step 5: Multiply the total population (5,000,000) by the decimal (0.80) to find the number of people to be vaccinated.
Step 6: Calculate 5,000,000 * 0.80, which equals 4,000,000.
