What is 2.05 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 2.05% of the output value, so we can write it down as x=2.05%.
5. Now we have two simple equations:
1) 2.5=100%
2) x=2.05%
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%/2.05%
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 2.05% of 2.5

2.5/x=100/2.05
(2.5/x)*x=(100/2.05)*x       - we multiply both sides of the equation by x
2.5=48.780487804878*x       - we divide both sides of the equation by (48.780487804878) to get x
2.5/48.780487804878=x
0.05125=x
x=0.05125

now we have:
2.05% of 2.5=0.05125
