What is 0.123 percent of 250000 - 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 250000 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 250000 is 100%, so we can write it down as 250000=100%.
4. We know, that x is 0.123% of the output value, so we can write it down as x=0.123%.
5. Now we have two simple equations:
1) 250000=100%
2) x=0.123%
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:
250000/x=100%/0.123%
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 0.123% of 250000

250000/x=100/0.123
(250000/x)*x=(100/0.123)*x       - we multiply both sides of the equation by x
250000=813.0081300813*x       - we divide both sides of the equation by (813.0081300813) to get x
250000/813.0081300813=x
307.5=x
x=307.5

now we have:
0.123% of 250000=307.5
