What is 3.95 percent of 7.99 - 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 7.99 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 7.99 is 100%, so we can write it down as 7.99=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) 7.99=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:
7.99/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 7.99

7.99/x=100/3.95
(7.99/x)*x=(100/3.95)*x       - we multiply both sides of the equation by x
7.99=25.316455696203*x       - we divide both sides of the equation by (25.316455696203) to get x
7.99/25.316455696203=x
0.315605=x
x=0.315605

now we have:
3.95% of 7.99=0.315605
