What is 3.17 percent of 126 - 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 126 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 126 is 100%, so we can write it down as 126=100%.
4. We know, that x is 3.17% of the output value, so we can write it down as x=3.17%.
5. Now we have two simple equations:
1) 126=100%
2) x=3.17%
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:
126/x=100%/3.17%
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 3.17% of 126

126/x=100/3.17
(126/x)*x=(100/3.17)*x       - we multiply both sides of the equation by x
126=31.545741324921*x       - we divide both sides of the equation by (31.545741324921) to get x
126/31.545741324921=x
3.9942=x
x=3.9942

now we have:
3.17% of 126=3.9942
