18.1 is what percent of 63 - 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 63 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 63, so we can write it down as 100%=63.
4. We know, that x% equals 18.1 of the output value, so we can write it down as x%=18.1.
5. Now we have two simple equations:
1) 100%=63
2) x%=18.1
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%=63/18.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.1 is what percent of 63

100%/x%=63/18.1
(100/x)*x=(63/18.1)*x       - we multiply both sides of the equation by x
100=3.4806629834254*x       - we divide both sides of the equation by (3.4806629834254) to get x
100/3.4806629834254=x
28.730158730159=x
x=28.730158730159

now we have:
18.1 is 28.730158730159% of 63
