412.7 is what percent of 510 - 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 510 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 510, so we can write it down as 100%=510.
4. We know, that x% equals 412.7 of the output value, so we can write it down as x%=412.7.
5. Now we have two simple equations:
1) 100%=510
2) x%=412.7
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%=510/412.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 412.7 is what percent of 510

100%/x%=510/412.7
(100/x)*x=(510/412.7)*x       - we multiply both sides of the equation by x
100=1.2357644778289*x       - we divide both sides of the equation by (1.2357644778289) to get x
100/1.2357644778289=x
80.921568627451=x
x=80.921568627451

now we have:
412.7 is 80.921568627451% of 510
