510.75 is what percent of 6450 - 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 6450 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 6450, so we can write it down as 100%=6450.
4. We know, that x% equals 510.75 of the output value, so we can write it down as x%=510.75.
5. Now we have two simple equations:
1) 100%=6450
2) x%=510.75
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%=6450/510.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 510.75 is what percent of 6450

100%/x%=6450/510.75
(100/x)*x=(6450/510.75)*x       - we multiply both sides of the equation by x
100=12.628487518355*x       - we divide both sides of the equation by (12.628487518355) to get x
100/12.628487518355=x
7.9186046511628=x
x=7.9186046511628

now we have:
510.75 is 7.9186046511628% of 6450
