A town has a population of 450000 people. If 60% of the population are under 25 years of age, how many people in the town are 25 years old and over?
If 60% of the population are under 25 years of age, then 100% - 60% = 40% of the population are 25 years old and over.
The total population of people who are 25 years old and over is 450000 x 40/100 = <<450000*40/100=180000>>180000. Answer: \boxed{180000}.
To find out how many people in the town are 25 years old and over, we need to determine the number of people who are under 25 years old first.
Given that 60% of the population are under 25 years old, we can calculate this by multiplying the population by 0.6:
Number of people under 25 = 450000 * 0.6 = 270000.
Now, let's find the number of people who are 25 years old and over. This can be calculated by subtracting the number of people under 25 from the total population:
Number of people 25 years old and over = 450000 - 270000 = 180000.
Therefore, there are 180,000 people in the town who are 25 years old and over.
To find out how many people in the town are 25 years old and over, we first need to find the number of people in the town who are under 25 years of age.
Given that 60% of the population are under 25 years old, we can calculate this by multiplying the total population by 0.60:
450,000 * 0.60 = 270,000
So, there are 270,000 people in the town who are under 25 years old.
To find out the number of people who are 25 years old and over, we subtract this number from the total population:
450,000 - 270,000 = 180,000
Therefore, in the town, there are 180,000 people who are 25 years old and over.
