What is 2100 percent of 90000 - 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 90000 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 90000 is 100%, so we can write it down as 90000=100%.
4. We know, that x is 2100% of the output value, so we can write it down as x=2100%.
5. Now we have two simple equations:
1) 90000=100%
2) x=2100%
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:
90000/x=100%/2100%
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 2100% of 90000

90000/x=100/2100
(90000/x)*x=(100/2100)*x       - we multiply both sides of the equation by x
90000=0.047619047619048*x       - we divide both sides of the equation by (0.047619047619048) to get x
90000/0.047619047619048=x
1890000=x
x=1890000

now we have:
2100% of 90000=1890000
