18.4 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 18.4 of the output value, so we can write it down as x%=18.4.
5. Now we have two simple equations:
1) 100%=63
2) x%=18.4
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%=63/18.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.4 is what percent of 63

100%/x%=63/18.4
(100/x)*x=(63/18.4)*x       - we multiply both sides of the equation by x
100=3.4239130434783*x       - we divide both sides of the equation by (3.4239130434783) to get x
100/3.4239130434783=x
29.206349206349=x
x=29.206349206349

now we have:
18.4 is 29.206349206349% of 63
