Question

What is the percent of increase from 22.2 to 99.9?

Write your answer using a percent sign (%).

Answer 1

450%

Explanation:

We can see that 22.2 is multiplied by 4.5 to get to 99.9, so we need to convert it to a percentage. To convert decimals to a percentage, we always move the decimal place to the right by 2 to get our percentage.

Answer 2

405%

Explanation:

99.9 / 22.2 = 4.5

4.5 as a percentage would be 405% because you move the decimal point two spaces to the right when making it a percentage.
