I have a world population of 1591000000 in 1950 and a population of 4028000000 in 2000. I need to know the percent of increase.
First I subtract 1591 from 4028= 2,437,000,000 and then I divide that by 1,591,000,000, which equals 1.53174104336.
Where do I go from here?
You have a good start. To make 1.53174104336 into percent form, multiply by 100:
100*1.53174104336 = 153.174104336%

To find the percent increase, you need to calculate the percentage change between the two population figures and express it as a percentage. Here's how you can proceed:
1. Calculate the difference in population: 4028 - 1591 = 2437 million.
2. Divide the difference by the original population: 2437 / 1591 = 1.5317.
3. Multiply the result by 100 to convert it to a percentage: 1.5317 * 100 = 153.17%.
Therefore, the percent increase in population between 1950 and 2000 is approximately 153.17%.
