What is 30.45 percent of 8.1 - 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 8.1 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 8.1 is 100%, so we can write it down as 8.1=100%.
4. We know, that x is 30.45% of the output value, so we can write it down as x=30.45%.
5. Now we have two simple equations:
1) 8.1=100%
2) x=30.45%
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:
8.1/x=100%/30.45%
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 30.45% of 8.1

8.1/x=100/30.45
(8.1/x)*x=(100/30.45)*x       - we multiply both sides of the equation by x
8.1=3.2840722495895*x       - we divide both sides of the equation by (3.2840722495895) to get x
8.1/3.2840722495895=x
2.46645=x
x=2.46645

now we have:
30.45% of 8.1=2.46645
