What is 3.17 percent of 21.06 - 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 21.06 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 21.06 is 100%, so we can write it down as 21.06=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) 21.06=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:
21.06/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 21.06

21.06/x=100/3.17
(21.06/x)*x=(100/3.17)*x       - we multiply both sides of the equation by x
21.06=31.545741324921*x       - we divide both sides of the equation by (31.545741324921) to get x
21.06/31.545741324921=x
0.667602=x
x=0.667602

now we have:
3.17% of 21.06=0.667602
