What is 900000000 percent of 7100000000 - 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 7100000000 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 7100000000 is 100%, so we can write it down as 7100000000=100%.
4. We know, that x is 900000000% of the output value, so we can write it down as x=900000000%.
5. Now we have two simple equations:
1) 7100000000=100%
2) x=900000000%
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:
7100000000/x=100%/900000000%
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 900000000% of 7100000000

7100000000/x=100/900000000
(7100000000/x)*x=(100/900000000)*x       - we multiply both sides of the equation by x
7100000000=1.1111111111111E-7*x       - we divide both sides of the equation by (1.1111111111111E-7) to get x
7100000000/1.1111111111111E-7=x
6.39E+16=x
x=6.39E+16

now we have:
900000000% of 7100000000=6.39E+16
