What is 4 percent of 3943.68 - 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 3943.68 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 3943.68 is 100%, so we can write it down as 3943.68=100%.
4. We know, that x is 4% of the output value, so we can write it down as x=4%.
5. Now we have two simple equations:
1) 3943.68=100%
2) x=4%
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:
3943.68/x=100%/4%
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 4% of 3943.68

3943.68/x=100/4
(3943.68/x)*x=(100/4)*x       - we multiply both sides of the equation by x
3943.68=25*x       - we divide both sides of the equation by (25) to get x
3943.68/25=x
157.7472=x
x=157.7472

now we have:
4% of 3943.68=157.7472
