What is 30000000 percent of 900000000 - 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 900000000 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 900000000 is 100%, so we can write it down as 900000000=100%.
4. We know, that x is 30000000% of the output value, so we can write it down as x=30000000%.
5. Now we have two simple equations:
1) 900000000=100%
2) x=30000000%
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:
900000000/x=100%/30000000%
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 30000000% of 900000000

900000000/x=100/30000000
(900000000/x)*x=(100/30000000)*x       - we multiply both sides of the equation by x
900000000=3.3333333333333E-6*x       - we divide both sides of the equation by (3.3333333333333E-6) to get x
900000000/3.3333333333333E-6=x
2.7E+14=x
x=2.7E+14

now we have:
30000000% of 900000000=2.7E+14
