866.6 is what percent of 700 - 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 700 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 700, so we can write it down as 100%=700.
4. We know, that x% equals 866.6 of the output value, so we can write it down as x%=866.6.
5. Now we have two simple equations:
1) 100%=700
2) x%=866.6
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%=700/866.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 866.6 is what percent of 700

100%/x%=700/866.6
(100/x)*x=(700/866.6)*x       - we multiply both sides of the equation by x
100=0.80775444264943*x       - we divide both sides of the equation by (0.80775444264943) to get x
100/0.80775444264943=x
123.8=x
x=123.8

now we have:
866.6 is 123.8% of 700
