What is 18.1 percent of 305 - 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 305 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 305 is 100%, so we can write it down as 305=100%.
4. We know, that x is 18.1% of the output value, so we can write it down as x=18.1%.
5. Now we have two simple equations:
1) 305=100%
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:
305/x=100%/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 what is 18.1% of 305

305/x=100/18.1
(305/x)*x=(100/18.1)*x       - we multiply both sides of the equation by x
305=5.524861878453*x       - we divide both sides of the equation by (5.524861878453) to get x
305/5.524861878453=x
55.205=x
x=55.205

now we have:
18.1% of 305=55.205
