What is 3.99 percent of 228 - 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 228 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 228 is 100%, so we can write it down as 228=100%.
4. We know, that x is 3.99% of the output value, so we can write it down as x=3.99%.
5. Now we have two simple equations:
1) 228=100%
2) x=3.99%
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:
228/x=100%/3.99%
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 3.99% of 228

228/x=100/3.99
(228/x)*x=(100/3.99)*x       - we multiply both sides of the equation by x
228=25.062656641604*x       - we divide both sides of the equation by (25.062656641604) to get x
228/25.062656641604=x
9.0972=x
x=9.0972

now we have:
3.99% of 228=9.0972
