What is 6 percent of 21.18 - 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 21.18 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 21.18 is 100%, so we can write it down as 21.18=100%.
4. We know, that x is 6% of the output value, so we can write it down as x=6%.
5. Now we have two simple equations:
1) 21.18=100%
2) x=6%
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:
21.18/x=100%/6%
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 6% of 21.18

21.18/x=100/6
(21.18/x)*x=(100/6)*x       - we multiply both sides of the equation by x
21.18=16.666666666667*x       - we divide both sides of the equation by (16.666666666667) to get x
21.18/16.666666666667=x
1.2708=x
x=1.2708

now we have:
6% of 21.18=1.2708
