What is 3.65 percent of 438 - 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 438 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 438 is 100%, so we can write it down as 438=100%.
4. We know, that x is 3.65% of the output value, so we can write it down as x=3.65%.
5. Now we have two simple equations:
1) 438=100%
2) x=3.65%
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:
438/x=100%/3.65%
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 3.65% of 438

438/x=100/3.65
(438/x)*x=(100/3.65)*x       - we multiply both sides of the equation by x
438=27.397260273973*x       - we divide both sides of the equation by (27.397260273973) to get x
438/27.397260273973=x
15.987=x
x=15.987

now we have:
3.65% of 438=15.987
