What is 820 percent of 20720 - 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 20720 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 20720 is 100%, so we can write it down as 20720=100%.
4. We know, that x is 820% of the output value, so we can write it down as x=820%.
5. Now we have two simple equations:
1) 20720=100%
2) x=820%
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:
20720/x=100%/820%
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 820% of 20720

20720/x=100/820
(20720/x)*x=(100/820)*x       - we multiply both sides of the equation by x
20720=0.1219512195122*x       - we divide both sides of the equation by (0.1219512195122) to get x
20720/0.1219512195122=x
169904=x
x=169904

now we have:
820% of 20720=169904
