What is 82 percent of 31.45 - 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 31.45 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 31.45 is 100%, so we can write it down as 31.45=100%.
4. We know, that x is 82% of the output value, so we can write it down as x=82%.
5. Now we have two simple equations:
1) 31.45=100%
2) x=82%
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:
31.45/x=100%/82%
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 82% of 31.45

31.45/x=100/82
(31.45/x)*x=(100/82)*x       - we multiply both sides of the equation by x
31.45=1.219512195122*x       - we divide both sides of the equation by (1.219512195122) to get x
31.45/1.219512195122=x
25.789=x
x=25.789

now we have:
82% of 31.45=25.789
