211.5 is what percent of 772 - 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 772 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 772, so we can write it down as 100%=772.
4. We know, that x% equals 211.5 of the output value, so we can write it down as x%=211.5.
5. Now we have two simple equations:
1) 100%=772
2) x%=211.5
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%=772/211.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 211.5 is what percent of 772

100%/x%=772/211.5
(100/x)*x=(772/211.5)*x       - we multiply both sides of the equation by x
100=3.6501182033097*x       - we divide both sides of the equation by (3.6501182033097) to get x
100/3.6501182033097=x
27.396373056995=x
x=27.396373056995

now we have:
211.5 is 27.396373056995% of 772
