What is 45000 percent of 309000 - 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 309000 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 309000 is 100%, so we can write it down as 309000=100%.
4. We know, that x is 45000% of the output value, so we can write it down as x=45000%.
5. Now we have two simple equations:
1) 309000=100%
2) x=45000%
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:
309000/x=100%/45000%
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 45000% of 309000

309000/x=100/45000
(309000/x)*x=(100/45000)*x       - we multiply both sides of the equation by x
309000=0.0022222222222222*x       - we divide both sides of the equation by (0.0022222222222222) to get x
309000/0.0022222222222222=x
139050000=x
x=139050000

now we have:
45000% of 309000=139050000
