66.45 is what percent of 500000 - 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 500000 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 500000, so we can write it down as 100%=500000.
4. We know, that x% equals 66.45 of the output value, so we can write it down as x%=66.45.
5. Now we have two simple equations:
1) 100%=500000
2) x%=66.45
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%=500000/66.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.45 is what percent of 500000

100%/x%=500000/66.45
(100/x)*x=(500000/66.45)*x       - we multiply both sides of the equation by x
100=7524.4544770504*x       - we divide both sides of the equation by (7524.4544770504) to get x
100/7524.4544770504=x
0.01329=x
x=0.01329

now we have:
66.45 is 0.01329% of 500000
