What is 21 percent of 55257.31 - 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 55257.31 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 55257.31 is 100%, so we can write it down as 55257.31=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) 55257.31=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:
55257.31/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 55257.31

55257.31/x=100/21
(55257.31/x)*x=(100/21)*x       - we multiply both sides of the equation by x
55257.31=4.7619047619048*x       - we divide both sides of the equation by (4.7619047619048) to get x
55257.31/4.7619047619048=x
11604.0351=x
x=11604.0351

now we have:
21% of 55257.31=11604.0351
