What is 12.29 percent of 820 - 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 820 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 820 is 100%, so we can write it down as 820=100%.
4. We know, that x is 12.29% of the output value, so we can write it down as x=12.29%.
5. Now we have two simple equations:
1) 820=100%
2) x=12.29%
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:
820/x=100%/12.29%
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 12.29% of 820

820/x=100/12.29
(820/x)*x=(100/12.29)*x       - we multiply both sides of the equation by x
820=8.1366965012205*x       - we divide both sides of the equation by (8.1366965012205) to get x
820/8.1366965012205=x
100.778=x
x=100.778

now we have:
12.29% of 820=100.778
