18 is what percent of 54.247 - 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 54.247 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 54.247, so we can write it down as 100%=54.247.
4. We know, that x% equals 18 of the output value, so we can write it down as x%=18.
5. Now we have two simple equations:
1) 100%=54.247
2) x%=18
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%=54.247/18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18 is what percent of 54.247

100%/x%=54.247/18
(100/x)*x=(54.247/18)*x       - we multiply both sides of the equation by x
100=3.0137222222222*x       - we divide both sides of the equation by (3.0137222222222) to get x
100/3.0137222222222=x
33.181558427194=x
x=33.181558427194

now we have:
18 is 33.181558427194% of 54.247
