What is 15.31 percent of 3.15 - 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 3.15 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 3.15 is 100%, so we can write it down as 3.15=100%.
4. We know, that x is 15.31% of the output value, so we can write it down as x=15.31%.
5. Now we have two simple equations:
1) 3.15=100%
2) x=15.31%
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:
3.15/x=100%/15.31%
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 15.31% of 3.15

3.15/x=100/15.31
(3.15/x)*x=(100/15.31)*x       - we multiply both sides of the equation by x
3.15=6.5316786414108*x       - we divide both sides of the equation by (6.5316786414108) to get x
3.15/6.5316786414108=x
0.482265=x
x=0.482265

now we have:
15.31% of 3.15=0.482265
