18 is what percent of 346 - 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 346 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 346, so we can write it down as 100%=346.
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%=346
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%=346/18
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 346

100%/x%=346/18
(100/x)*x=(346/18)*x       - we multiply both sides of the equation by x
100=19.222222222222*x       - we divide both sides of the equation by (19.222222222222) to get x
100/19.222222222222=x
5.2023121387283=x
x=5.2023121387283

now we have:
18 is 5.2023121387283% of 346
