What is 0.3 percent of 81000 - 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 81000 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 81000 is 100%, so we can write it down as 81000=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) 81000=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:
81000/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 81000

81000/x=100/0.3
(81000/x)*x=(100/0.3)*x       - we multiply both sides of the equation by x
81000=333.33333333333*x       - we divide both sides of the equation by (333.33333333333) to get x
81000/333.33333333333=x
243=x
x=243

now we have:
0.3% of 81000=243
