What is 47.21 percent of 20.31 - 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 20.31 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 20.31 is 100%, so we can write it down as 20.31=100%.
4. We know, that x is 47.21% of the output value, so we can write it down as x=47.21%.
5. Now we have two simple equations:
1) 20.31=100%
2) x=47.21%
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:
20.31/x=100%/47.21%
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 47.21% of 20.31

20.31/x=100/47.21
(20.31/x)*x=(100/47.21)*x       - we multiply both sides of the equation by x
20.31=2.1181952976064*x       - we divide both sides of the equation by (2.1181952976064) to get x
20.31/2.1181952976064=x
9.588351=x
x=9.588351

now we have:
47.21% of 20.31=9.588351
