210.85 is what percent of 858.25 - 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 858.25 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 100% equals 858.25, so we can write it down as 100%=858.25.
4. We know, that x% equals 210.85 of the output value, so we can write it down as x%=210.85.
5. Now we have two simple equations:
1) 100%=858.25
2) x%=210.85
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:
100%/x%=858.25/210.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 210.85 is what percent of 858.25

100%/x%=858.25/210.85
(100/x)*x=(858.25/210.85)*x       - we multiply both sides of the equation by x
100=4.0704292150818*x       - we divide both sides of the equation by (4.0704292150818) to get x
100/4.0704292150818=x
24.56743373143=x
x=24.56743373143

now we have:
210.85 is 24.56743373143% of 858.25
