18.4 is what percent of 53.4 - 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 53.4 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 53.4, so we can write it down as 100%=53.4.
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%=53.4
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%=53.4/18.4
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 53.4

100%/x%=53.4/18.4
(100/x)*x=(53.4/18.4)*x       - we multiply both sides of the equation by x
100=2.9021739130435*x       - we divide both sides of the equation by (2.9021739130435) to get x
100/2.9021739130435=x
34.456928838951=x
x=34.456928838951

now we have:
18.4 is 34.456928838951% of 53.4
