8.25 is what percent of 0.2 - 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 0.2 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 100% equals 0.2, so we can write it down as 100%=0.2.
4. We know, that x% equals 8.25 of the output value, so we can write it down as x%=8.25.
5. Now we have two simple equations:
1) 100%=0.2
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:
100%/x%=0.2/8.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.25 is what percent of 0.2

100%/x%=0.2/8.25
(100/x)*x=(0.2/8.25)*x       - we multiply both sides of the equation by x
100=0.024242424242424*x       - we divide both sides of the equation by (0.024242424242424) to get x
100/0.024242424242424=x
4125=x
x=4125

now we have:
8.25 is 4125% of 0.2
