What is 77 percent of 525 - 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 525 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 525 is 100%, so we can write it down as 525=100%.
4. We know, that x is 77% of the output value, so we can write it down as x=77%.
5. Now we have two simple equations:
1) 525=100%
2) x=77%
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:
525/x=100%/77%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 77% of 525

525/x=100/77
(525/x)*x=(100/77)*x       - we multiply both sides of the equation by x
525=1.2987012987013*x       - we divide both sides of the equation by (1.2987012987013) to get x
525/1.2987012987013=x
404.25=x
x=404.25

now we have:
77% of 525=404.25
