18 is what percent of 236930 - 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 236930 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 236930, so we can write it down as 100%=236930.
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%=236930
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%=236930/18
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 236930

100%/x%=236930/18
(100/x)*x=(236930/18)*x       - we multiply both sides of the equation by x
100=13162.777777778*x       - we divide both sides of the equation by (13162.777777778) to get x
100/13162.777777778=x
0.0075971806018655=x
x=0.0075971806018655

now we have:
