What is 5.858 percent of 8.421 - 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 8.421 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 8.421 is 100%, so we can write it down as 8.421=100%.
4. We know, that x is 5.858% of the output value, so we can write it down as x=5.858%.
5. Now we have two simple equations:
1) 8.421=100%
2) x=5.858%
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:
8.421/x=100%/5.858%
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 5.858% of 8.421

8.421/x=100/5.858
(8.421/x)*x=(100/5.858)*x       - we multiply both sides of the equation by x
8.421=17.0706725845*x       - we divide both sides of the equation by (17.0706725845) to get x
8.421/17.0706725845=x
0.49330218=x
x=0.49330218

now we have:
5.858% of 8.421=0.49330218
