What is 9.3 percent of 21.16 - 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 21.16 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 21.16 is 100%, so we can write it down as 21.16=100%.
4. We know, that x is 9.3% of the output value, so we can write it down as x=9.3%.
5. Now we have two simple equations:
1) 21.16=100%
2) x=9.3%
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:
21.16/x=100%/9.3%
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 9.3% of 21.16

21.16/x=100/9.3
(21.16/x)*x=(100/9.3)*x       - we multiply both sides of the equation by x
21.16=10.752688172043*x       - we divide both sides of the equation by (10.752688172043) to get x
21.16/10.752688172043=x
1.96788=x
x=1.96788

now we have:
9.3% of 21.16=1.96788
