What is 21.05 percent of 100000 - 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 100000 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 100000 is 100%, so we can write it down as 100000=100%.
4. We know, that x is 21.05% of the output value, so we can write it down as x=21.05%.
5. Now we have two simple equations:
1) 100000=100%
2) x=21.05%
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:
100000/x=100%/21.05%
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 21.05% of 100000

100000/x=100/21.05
(100000/x)*x=(100/21.05)*x       - we multiply both sides of the equation by x
100000=4.750593824228*x       - we divide both sides of the equation by (4.750593824228) to get x
100000/4.750593824228=x
21050=x
x=21050

now we have:
21.05% of 100000=21050
