412.5 is what percent of 8250 - 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 8250 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 8250, so we can write it down as 100%=8250.
4. We know, that x% equals 412.5 of the output value, so we can write it down as x%=412.5.
5. Now we have two simple equations:
1) 100%=8250
2) x%=412.5
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%=8250/412.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 412.5 is what percent of 8250

100%/x%=8250/412.5
(100/x)*x=(8250/412.5)*x       - we multiply both sides of the equation by x
100=20*x       - we divide both sides of the equation by (20) to get x
100/20=x
5=x
x=5

now we have:
412.5 is 5% of 8250
