What is 42009 percent of 2.5 - 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 2.5 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 2.5 is 100%, so we can write it down as 2.5=100%.
4. We know, that x is 42009% of the output value, so we can write it down as x=42009%.
5. Now we have two simple equations:
1) 2.5=100%
2) x=42009%
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:
2.5/x=100%/42009%
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 42009% of 2.5

2.5/x=100/42009
(2.5/x)*x=(100/42009)*x       - we multiply both sides of the equation by x
2.5=0.0023804422861768*x       - we divide both sides of the equation by (0.0023804422861768) to get x
2.5/0.0023804422861768=x
1050.225=x
x=1050.225

now we have:
42009% of 2.5=1050.225
