What is 0.058 percent of 399 - 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 399 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 399 is 100%, so we can write it down as 399=100%.
4. We know, that x is 0.058% of the output value, so we can write it down as x=0.058%.
5. Now we have two simple equations:
1) 399=100%
2) x=0.058%
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:
399/x=100%/0.058%
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 0.058% of 399

399/x=100/0.058
(399/x)*x=(100/0.058)*x       - we multiply both sides of the equation by x
399=1724.1379310345*x       - we divide both sides of the equation by (1724.1379310345) to get x
399/1724.1379310345=x
0.23142=x
x=0.23142

now we have:
0.058% of 399=0.23142
