7.13 is what 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 100% equals 820, so we can write it down as 100%=820.
4. We know, that x% equals 7.13 of the output value, so we can write it down as x%=7.13.
5. Now we have two simple equations:
1) 100%=820
2) x%=7.13
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%=820/7.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.13 is what percent of 820

100%/x%=820/7.13
(100/x)*x=(820/7.13)*x       - we multiply both sides of the equation by x
100=115.00701262272*x       - we divide both sides of the equation by (115.00701262272) to get x
100/115.00701262272=x
0.86951219512195=x
x=0.86951219512195

now we have:
7.13 is 0.86951219512195% of 820
