What is 1.25 percent of 16.86 - 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 16.86 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 16.86 is 100%, so we can write it down as 16.86=100%.
4. We know, that x is 1.25% of the output value, so we can write it down as x=1.25%.
5. Now we have two simple equations:
1) 16.86=100%
2) x=1.25%
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:
16.86/x=100%/1.25%
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 1.25% of 16.86

16.86/x=100/1.25
(16.86/x)*x=(100/1.25)*x       - we multiply both sides of the equation by x
16.86=80*x       - we divide both sides of the equation by (80) to get x
16.86/80=x
0.21075=x
x=0.21075

now we have:
1.25% of 16.86=0.21075
