What is 13.7 percent of 28.18 - 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 28.18 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 28.18 is 100%, so we can write it down as 28.18=100%.
4. We know, that x is 13.7% of the output value, so we can write it down as x=13.7%.
5. Now we have two simple equations:
1) 28.18=100%
2) x=13.7%
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:
28.18/x=100%/13.7%
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 13.7% of 28.18

28.18/x=100/13.7
(28.18/x)*x=(100/13.7)*x       - we multiply both sides of the equation by x
28.18=7.2992700729927*x       - we divide both sides of the equation by (7.2992700729927) to get x
28.18/7.2992700729927=x
3.86066=x
x=3.86066

now we have:
13.7% of 28.18=3.86066
