18 is what percent of 57400 - 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 57400 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 57400, so we can write it down as 100%=57400.
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%=57400
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%=57400/18
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 57400

100%/x%=57400/18
(100/x)*x=(57400/18)*x       - we multiply both sides of the equation by x
100=3188.8888888889*x       - we divide both sides of the equation by (3188.8888888889) to get x
100/3188.8888888889=x
0.031358885017422=x
x=0.031358885017422

now we have:
18 is 0.031358885017422% of 57400
