18 is what percent of 54.02 - 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 54.02 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 54.02, so we can write it down as 100%=54.02.
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%=54.02
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%=54.02/18
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 54.02

100%/x%=54.02/18
(100/x)*x=(54.02/18)*x       - we multiply both sides of the equation by x
100=3.0011111111111*x       - we divide both sides of the equation by (3.0011111111111) to get x
100/3.0011111111111=x
33.320992225102=x
x=33.320992225102

now we have:
18 is 33.320992225102% of 54.02
