What is 0.3 percent of 45000000000 - 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 45000000000 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 45000000000 is 100%, so we can write it down as 45000000000=100%.
4. We know, that x is 0.3% of the output value, so we can write it down as x=0.3%.
5. Now we have two simple equations:
1) 45000000000=100%
2) x=0.3%
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:
45000000000/x=100%/0.3%
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 0.3% of 45000000000

45000000000/x=100/0.3
(45000000000/x)*x=(100/0.3)*x       - we multiply both sides of the equation by x
45000000000=333.33333333333*x       - we divide both sides of the equation by (333.33333333333) to get x
45000000000/333.33333333333=x
135000000=x
x=135000000

now we have:
0.3% of 45000000000=135000000
