What is 2.81 percent of 150000 - 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 150000 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 150000 is 100%, so we can write it down as 150000=100%.
4. We know, that x is 2.81% of the output value, so we can write it down as x=2.81%.
5. Now we have two simple equations:
1) 150000=100%
2) x=2.81%
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:
150000/x=100%/2.81%
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 2.81% of 150000

150000/x=100/2.81
(150000/x)*x=(100/2.81)*x       - we multiply both sides of the equation by x
150000=35.5871886121*x       - we divide both sides of the equation by (35.5871886121) to get x
150000/35.5871886121=x
4215=x
x=4215

now we have:
2.81% of 150000=4215
