4 is what percent of 8538 - 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 8538 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 8538, so we can write it down as 100%=8538.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=8538
2) x%=4
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%=8538/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 8538

100%/x%=8538/4
(100/x)*x=(8538/4)*x       - we multiply both sides of the equation by x
100=2134.5*x       - we divide both sides of the equation by (2134.5) to get x
100/2134.5=x
0.046849379245725=x
x=0.046849379245725

now we have:
4 is 0.046849379245725% of 8538
