What is 1.011 percent of 390 - 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 390 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 390 is 100%, so we can write it down as 390=100%.
4. We know, that x is 1.011% of the output value, so we can write it down as x=1.011%.
5. Now we have two simple equations:
1) 390=100%
2) x=1.011%
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:
390/x=100%/1.011%
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 1.011% of 390

390/x=100/1.011
(390/x)*x=(100/1.011)*x       - we multiply both sides of the equation by x
390=98.91196834817*x       - we divide both sides of the equation by (98.91196834817) to get x
390/98.91196834817=x
3.9429=x
x=3.9429

now we have:
1.011% of 390=3.9429
