What is 21000 percent of 15000 - 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 15000 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 15000 is 100%, so we can write it down as 15000=100%.
4. We know, that x is 21000% of the output value, so we can write it down as x=21000%.
5. Now we have two simple equations:
1) 15000=100%
2) x=21000%
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:
15000/x=100%/21000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 21000% of 15000

15000/x=100/21000
(15000/x)*x=(100/21000)*x       - we multiply both sides of the equation by x
15000=0.0047619047619048*x       - we divide both sides of the equation by (0.0047619047619048) to get x
15000/0.0047619047619048=x
3150000=x
x=3150000

now we have:
21000% of 15000=3150000
