51.2 is what percent of 187 - 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 187 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 187, so we can write it down as 100%=187.
4. We know, that x% equals 51.2 of the output value, so we can write it down as x%=51.2.
5. Now we have two simple equations:
1) 100%=187
2) x%=51.2
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%=187/51.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51.2 is what percent of 187

100%/x%=187/51.2
(100/x)*x=(187/51.2)*x       - we multiply both sides of the equation by x
100=3.65234375*x       - we divide both sides of the equation by (3.65234375) to get x
100/3.65234375=x
27.379679144385=x
x=27.379679144385

now we have:
51.2 is 27.379679144385% of 187
