220.5 is what percent of 2070 - 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 2070 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 2070, so we can write it down as 100%=2070.
4. We know, that x% equals 220.5 of the output value, so we can write it down as x%=220.5.
5. Now we have two simple equations:
1) 100%=2070
2) x%=220.5
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%=2070/220.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 220.5 is what percent of 2070

100%/x%=2070/220.5
(100/x)*x=(2070/220.5)*x       - we multiply both sides of the equation by x
100=9.3877551020408*x       - we divide both sides of the equation by (9.3877551020408) to get x
100/9.3877551020408=x
10.652173913043=x
x=10.652173913043

now we have:
220.5 is 10.652173913043% of 2070
