7 is what percent of 20802 - 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 20802 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 20802, so we can write it down as 100%=20802.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=20802
2) x%=7
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%=20802/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 20802

100%/x%=20802/7
(100/x)*x=(20802/7)*x       - we multiply both sides of the equation by x
100=2971.7142857143*x       - we divide both sides of the equation by (2971.7142857143) to get x
100/2971.7142857143=x
0.033650610518219=x
x=0.033650610518219

now we have:
7 is 0.033650610518219% of 20802
