What is 509 percent of 489 - 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 489 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 489 is 100%, so we can write it down as 489=100%.
4. We know, that x is 509% of the output value, so we can write it down as x=509%.
5. Now we have two simple equations:
1) 489=100%
2) x=509%
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:
489/x=100%/509%
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 509% of 489

489/x=100/509
(489/x)*x=(100/509)*x       - we multiply both sides of the equation by x
489=0.19646365422397*x       - we divide both sides of the equation by (0.19646365422397) to get x
489/0.19646365422397=x
2489.01=x
x=2489.01

now we have:
509% of 489=2489.01
