Question

The population of spring field increased from 120,000 to 150,000. What percent does the increase represent ?

Answer 1

The simple way to calculate this is to divide the new number which the population increased to (the 150,000) by the original number (120,000), and multiply by 100 to give it as a percentage.

So, 100 x (150,000/120,000) = 125%.

So the new population is 125% the size of the original population, which means it increased by 25%.
