What is 8.25 percent of 245 - 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 245 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 245 is 100%, so we can write it down as 245=100%.
4. We know, that x is 8.25% of the output value, so we can write it down as x=8.25%.
5. Now we have two simple equations:
1) 245=100%
2) x=8.25%
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:
245/x=100%/8.25%
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 8.25% of 245

245/x=100/8.25
(245/x)*x=(100/8.25)*x       - we multiply both sides of the equation by x
245=12.121212121212*x       - we divide both sides of the equation by (12.121212121212) to get x
245/12.121212121212=x
20.2125=x
x=20.2125

now we have:
8.25% of 245=20.2125
