20.16 is what percent of 29.57 - 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 29.57 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 29.57, so we can write it down as 100%=29.57.
4. We know, that x% equals 20.16 of the output value, so we can write it down as x%=20.16.
5. Now we have two simple equations:
1) 100%=29.57
2) x%=20.16
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%=29.57/20.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.16 is what percent of 29.57

100%/x%=29.57/20.16
(100/x)*x=(29.57/20.16)*x       - we multiply both sides of the equation by x
100=1.4667658730159*x       - we divide both sides of the equation by (1.4667658730159) to get x
100/1.4667658730159=x
68.17720662834=x
x=68.17720662834

now we have:
20.16 is 68.17720662834% of 29.57
