What is 8.45 percent of 18 - 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 18 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 18 is 100%, so we can write it down as 18=100%.
4. We know, that x is 8.45% of the output value, so we can write it down as x=8.45%.
5. Now we have two simple equations:
1) 18=100%
2) x=8.45%
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:
18/x=100%/8.45%
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 8.45% of 18

18/x=100/8.45
(18/x)*x=(100/8.45)*x       - we multiply both sides of the equation by x
18=11.834319526627*x       - we divide both sides of the equation by (11.834319526627) to get x
18/11.834319526627=x
1.521=x
x=1.521

now we have:
8.45% of 18=1.521
