857.6 is what percent of 1010 - 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 1010 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 1010, so we can write it down as 100%=1010.
4. We know, that x% equals 857.6 of the output value, so we can write it down as x%=857.6.
5. Now we have two simple equations:
1) 100%=1010
2) x%=857.6
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%=1010/857.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 857.6 is what percent of 1010

100%/x%=1010/857.6
(100/x)*x=(1010/857.6)*x       - we multiply both sides of the equation by x
100=1.1777052238806*x       - we divide both sides of the equation by (1.1777052238806) to get x
100/1.1777052238806=x
84.910891089109=x
x=84.910891089109

now we have:
857.6 is 84.910891089109% of 1010
