What is 1.62 percent of 3.99 - 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 3.99 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 3.99 is 100%, so we can write it down as 3.99=100%.
4. We know, that x is 1.62% of the output value, so we can write it down as x=1.62%.
5. Now we have two simple equations:
1) 3.99=100%
2) x=1.62%
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:
3.99/x=100%/1.62%
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 1.62% of 3.99

3.99/x=100/1.62
(3.99/x)*x=(100/1.62)*x       - we multiply both sides of the equation by x
3.99=61.728395061728*x       - we divide both sides of the equation by (61.728395061728) to get x
3.99/61.728395061728=x
0.064638=x
x=0.064638

now we have:
1.62% of 3.99=0.064638
