What is 1.31 percent of 21.2 - 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 21.2 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 21.2 is 100%, so we can write it down as 21.2=100%.
4. We know, that x is 1.31% of the output value, so we can write it down as x=1.31%.
5. Now we have two simple equations:
1) 21.2=100%
2) x=1.31%
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:
21.2/x=100%/1.31%
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 1.31% of 21.2

21.2/x=100/1.31
(21.2/x)*x=(100/1.31)*x       - we multiply both sides of the equation by x
21.2=76.335877862595*x       - we divide both sides of the equation by (76.335877862595) to get x
21.2/76.335877862595=x
0.27772=x
x=0.27772

now we have:
1.31% of 21.2=0.27772
