18 is what percent of 5317 - 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 5317 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 5317, so we can write it down as 100%=5317.
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%=5317
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%=5317/18
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 5317

100%/x%=5317/18
(100/x)*x=(5317/18)*x       - we multiply both sides of the equation by x
100=295.38888888889*x       - we divide both sides of the equation by (295.38888888889) to get x
100/295.38888888889=x
0.33853676885462=x
x=0.33853676885462

now we have:
18 is 0.33853676885462% of 5317
