What is 13.21 percent of 3.71 - 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 3.71 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 3.71 is 100%, so we can write it down as 3.71=100%.
4. We know, that x is 13.21% of the output value, so we can write it down as x=13.21%.
5. Now we have two simple equations:
1) 3.71=100%
2) x=13.21%
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:
3.71/x=100%/13.21%
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 13.21% of 3.71

3.71/x=100/13.21
(3.71/x)*x=(100/13.21)*x       - we multiply both sides of the equation by x
3.71=7.5700227100681*x       - we divide both sides of the equation by (7.5700227100681) to get x
3.71/7.5700227100681=x
0.490091=x
x=0.490091

now we have:
13.21% of 3.71=0.490091
