What is 4.05 percent of 3.25 - 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 3.25 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 3.25 is 100%, so we can write it down as 3.25=100%.
4. We know, that x is 4.05% of the output value, so we can write it down as x=4.05%.
5. Now we have two simple equations:
1) 3.25=100%
2) x=4.05%
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:
3.25/x=100%/4.05%
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 4.05% of 3.25

3.25/x=100/4.05
(3.25/x)*x=(100/4.05)*x       - we multiply both sides of the equation by x
3.25=24.691358024691*x       - we divide both sides of the equation by (24.691358024691) to get x
3.25/24.691358024691=x
0.131625=x
x=0.131625

now we have:
4.05% of 3.25=0.131625
