18 is what percent of 12530 - 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 12530 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 12530, so we can write it down as 100%=12530.
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%=12530
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%=12530/18
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 12530

100%/x%=12530/18
(100/x)*x=(12530/18)*x       - we multiply both sides of the equation by x
100=696.11111111111*x       - we divide both sides of the equation by (696.11111111111) to get x
100/696.11111111111=x
0.14365522745411=x
x=0.14365522745411

now we have:
18 is 0.14365522745411% of 12530
