28.4 is what percent of 1000 - 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 1000 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 1000, so we can write it down as 100%=1000.
4. We know, that x% equals 28.4 of the output value, so we can write it down as x%=28.4.
5. Now we have two simple equations:
1) 100%=1000
2) x%=28.4
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%=1000/28.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.4 is what percent of 1000

100%/x%=1000/28.4
(100/x)*x=(1000/28.4)*x       - we multiply both sides of the equation by x
100=35.211267605634*x       - we divide both sides of the equation by (35.211267605634) to get x
100/35.211267605634=x
2.84=x
x=2.84

now we have:
28.4 is 2.84% of 1000
