21 is what percent of 19049 - 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 19049 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 19049, so we can write it down as 100%=19049.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=19049
2) x%=21
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%=19049/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21 is what percent of 19049

100%/x%=19049/21
(100/x)*x=(19049/21)*x       - we multiply both sides of the equation by x
100=907.09523809524*x       - we divide both sides of the equation by (907.09523809524) to get x
100/907.09523809524=x
0.11024200745446=x
x=0.11024200745446

now we have:
21 is 0.11024200745446% of 19049
