85 is what percent of 1858 - 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 1858 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 1858, so we can write it down as 100%=1858.
4. We know, that x% equals 85 of the output value, so we can write it down as x%=85.
5. Now we have two simple equations:
1) 100%=1858
2) x%=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%=1858/85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85 is what percent of 1858

100%/x%=1858/85
(100/x)*x=(1858/85)*x       - we multiply both sides of the equation by x
100=21.858823529412*x       - we divide both sides of the equation by (21.858823529412) to get x
100/21.858823529412=x
4.5748116254037=x
x=4.5748116254037

now we have:
85 is 4.5748116254037% of 1858
