What is 3.95 percent of 402 - 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 402 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 402 is 100%, so we can write it down as 402=100%.
4. We know, that x is 3.95% of the output value, so we can write it down as x=3.95%.
5. Now we have two simple equations:
1) 402=100%
2) x=3.95%
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:
402/x=100%/3.95%
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 3.95% of 402

402/x=100/3.95
(402/x)*x=(100/3.95)*x       - we multiply both sides of the equation by x
402=25.316455696203*x       - we divide both sides of the equation by (25.316455696203) to get x
402/25.316455696203=x
15.879=x
x=15.879

now we have:
3.95% of 402=15.879
