30.21 is what percent of 162.5 - 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 162.5 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 162.5, so we can write it down as 100%=162.5.
4. We know, that x% equals 30.21 of the output value, so we can write it down as x%=30.21.
5. Now we have two simple equations:
1) 100%=162.5
2) x%=30.21
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%=162.5/30.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.21 is what percent of 162.5

100%/x%=162.5/30.21
(100/x)*x=(162.5/30.21)*x       - we multiply both sides of the equation by x
100=5.379013571665*x       - we divide both sides of the equation by (5.379013571665) to get x
100/5.379013571665=x
18.590769230769=x
x=18.590769230769

now we have:
30.21 is 18.590769230769% of 162.5
