158.4 is what percent of 2000 - 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 2000 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 2000, so we can write it down as 100%=2000.
4. We know, that x% equals 158.4 of the output value, so we can write it down as x%=158.4.
5. Now we have two simple equations:
1) 100%=2000
2) x%=158.4
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%=2000/158.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 158.4 is what percent of 2000

100%/x%=2000/158.4
(100/x)*x=(2000/158.4)*x       - we multiply both sides of the equation by x
100=12.626262626263*x       - we divide both sides of the equation by (12.626262626263) to get x
100/12.626262626263=x
7.92=x
x=7.92

now we have:
158.4 is 7.92% of 2000
