What is 3.05 percent of 4 - 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 4 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 4 is 100%, so we can write it down as 4=100%.
4. We know, that x is 3.05% of the output value, so we can write it down as x=3.05%.
5. Now we have two simple equations:
1) 4=100%
2) x=3.05%
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:
4/x=100%/3.05%
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 3.05% of 4

4/x=100/3.05
(4/x)*x=(100/3.05)*x       - we multiply both sides of the equation by x
4=32.786885245902*x       - we divide both sides of the equation by (32.786885245902) to get x
4/32.786885245902=x
0.122=x
x=0.122

now we have:
3.05% of 4=0.122
