525.05 is what percent of 660 - 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 660 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 660, so we can write it down as 100%=660.
4. We know, that x% equals 525.05 of the output value, so we can write it down as x%=525.05.
5. Now we have two simple equations:
1) 100%=660
2) x%=525.05
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%=660/525.05
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 525.05 is what percent of 660

100%/x%=660/525.05
(100/x)*x=(660/525.05)*x       - we multiply both sides of the equation by x
100=1.2570231406533*x       - we divide both sides of the equation by (1.2570231406533) to get x
100/1.2570231406533=x
79.55303030303=x
x=79.55303030303

now we have:
525.05 is 79.55303030303% of 660
