19.5 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 19.5 of the output value, so we can write it down as x%=19.5.
5. Now we have two simple equations:
1) 100%=2000
2) x%=19.5
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%=2000/19.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.5 is what percent of 2000

100%/x%=2000/19.5
(100/x)*x=(2000/19.5)*x       - we multiply both sides of the equation by x
100=102.5641025641*x       - we divide both sides of the equation by (102.5641025641) to get x
100/102.5641025641=x
0.975=x
x=0.975

now we have:
19.5 is 0.975% of 2000
