What is 21 percent of 16.29 - 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 16.29 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 16.29 is 100%, so we can write it down as 16.29=100%.
4. We know, that x is 21% of the output value, so we can write it down as x=21%.
5. Now we have two simple equations:
1) 16.29=100%
2) x=21%
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:
16.29/x=100%/21%
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 21% of 16.29

16.29/x=100/21
(16.29/x)*x=(100/21)*x       - we multiply both sides of the equation by x
16.29=4.7619047619048*x       - we divide both sides of the equation by (4.7619047619048) to get x
16.29/4.7619047619048=x
3.4209=x
x=3.4209

now we have:
21% of 16.29=3.4209
