What is 2500 percent of 0.00022 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 0.00022 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 0.00022 is 100%, so we can write it down as 0.00022=100%.
4. We know, that x is 2500% of the output value, so we can write it down as x=2500%.
5. Now we have two simple equations:
1) 0.00022=100%
2) x=2500%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
0.00022/x=100%/2500%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2500% of 0.00022

0.00022/x=100/2500
(0.00022/x)*x=(100/2500)*x       - we multiply both sides of the equation by x
0.00022=0.04*x       - we divide both sides of the equation by (0.04) to get x
0.00022/0.04=x
0.0055=x
x=0.0055

now we have:
2500% of 0.00022=0.0055
