What is 6420 percent of 8720 - 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 8720 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 8720 is 100%, so we can write it down as 8720=100%.
4. We know, that x is 6420% of the output value, so we can write it down as x=6420%.
5. Now we have two simple equations:
1) 8720=100%
2) x=6420%
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:
8720/x=100%/6420%
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 6420% of 8720

8720/x=100/6420
(8720/x)*x=(100/6420)*x       - we multiply both sides of the equation by x
8720=0.015576323987539*x       - we divide both sides of the equation by (0.015576323987539) to get x
8720/0.015576323987539=x
559824=x
x=559824

now we have:
6420% of 8720=559824
