28.8 is what percent of 100000 - 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 100000 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 100000, so we can write it down as 100%=100000.
4. We know, that x% equals 28.8 of the output value, so we can write it down as x%=28.8.
5. Now we have two simple equations:
1) 100%=100000
2) x%=28.8
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%=100000/28.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.8 is what percent of 100000

100%/x%=100000/28.8
(100/x)*x=(100000/28.8)*x       - we multiply both sides of the equation by x
100=3472.2222222222*x       - we divide both sides of the equation by (3472.2222222222) to get x
100/3472.2222222222=x
0.0288=x
x=0.0288

now we have:
28.8 is 0.0288% of 100000
