What is 2100000 percent of 800000000 - 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 800000000 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 800000000 is 100%, so we can write it down as 800000000=100%.
4. We know, that x is 2100000% of the output value, so we can write it down as x=2100000%.
5. Now we have two simple equations:
1) 800000000=100%
2) x=2100000%
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:
800000000/x=100%/2100000%
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 2100000% of 800000000

800000000/x=100/2100000
(800000000/x)*x=(100/2100000)*x       - we multiply both sides of the equation by x
800000000=4.7619047619048E-5*x       - we divide both sides of the equation by (4.7619047619048E-5) to get x
800000000/4.7619047619048E-5=x
16800000000000=x
x=16800000000000

now we have:
2100000% of 800000000=16800000000000
