Question

In a population of 3 1/4 million people, 2115000 are under the age of 16. Calculate the percentage, to two decimal places, of the population who are under the age of 16

Answer 1

So what we need to do is divide the number of people under 16 by the number of the entire population:

$\frac{2115000}{3250000}$

first, let's get rid of the 0s:

$\frac{2115}{3250}$

now, we can divide:
 this is 0.6507....

in order to make this into a percentage, we multiply by 100%:

0.6507*100%=65.07%

the answer is: 65 % (quite a lot!!!)
