5 is what percent of 3858 - 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 3858 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 3858, so we can write it down as 100%=3858.
4. We know, that x% equals 5 of the output value, so we can write it down as x%=5.
5. Now we have two simple equations:
1) 100%=3858
2) x%=5
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%=3858/5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5 is what percent of 3858

100%/x%=3858/5
(100/x)*x=(3858/5)*x       - we multiply both sides of the equation by x
100=771.6*x       - we divide both sides of the equation by (771.6) to get x
100/771.6=x
0.12960082944531=x
x=0.12960082944531

now we have:
5 is 0.12960082944531% of 3858
