15 is what percent of 570000 - 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 570000 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 570000, so we can write it down as 100%=570000.
4. We know, that x% equals 15 of the output value, so we can write it down as x%=15.
5. Now we have two simple equations:
1) 100%=570000
2) x%=15
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%=570000/15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15 is what percent of 570000

100%/x%=570000/15
(100/x)*x=(570000/15)*x       - we multiply both sides of the equation by x
100=38000*x       - we divide both sides of the equation by (38000) to get x
100/38000=x
0.0026315789473684=x
x=0.0026315789473684

now we have:
15 is 0.0026315789473684% of 570000
