What is 1.2 percent of 509 - 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 509 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 509 is 100%, so we can write it down as 509=100%.
4. We know, that x is 1.2% of the output value, so we can write it down as x=1.2%.
5. Now we have two simple equations:
1) 509=100%
2) x=1.2%
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:
509/x=100%/1.2%
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 1.2% of 509

509/x=100/1.2
(509/x)*x=(100/1.2)*x       - we multiply both sides of the equation by x
509=83.333333333333*x       - we divide both sides of the equation by (83.333333333333) to get x
509/83.333333333333=x
6.108=x
x=6.108

now we have:
1.2% of 509=6.108
