What is 14 percent of 0.21 - 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 0.21 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 0.21 is 100%, so we can write it down as 0.21=100%.
4. We know, that x is 14% of the output value, so we can write it down as x=14%.
5. Now we have two simple equations:
1) 0.21=100%
2) x=14%
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:
0.21/x=100%/14%
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 14% of 0.21

0.21/x=100/14
(0.21/x)*x=(100/14)*x       - we multiply both sides of the equation by x
0.21=7.1428571428571*x       - we divide both sides of the equation by (7.1428571428571) to get x
0.21/7.1428571428571=x
0.0294=x
x=0.0294

now we have:
14% of 0.21=0.0294
