What is 27.8 percent of 0.18 - 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 0.18 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 0.18 is 100%, so we can write it down as 0.18=100%.
4. We know, that x is 27.8% of the output value, so we can write it down as x=27.8%.
5. Now we have two simple equations:
1) 0.18=100%
2) x=27.8%
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:
0.18/x=100%/27.8%
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 27.8% of 0.18

0.18/x=100/27.8
(0.18/x)*x=(100/27.8)*x       - we multiply both sides of the equation by x
0.18=3.5971223021583*x       - we divide both sides of the equation by (3.5971223021583) to get x
0.18/3.5971223021583=x
0.05004=x
x=0.05004

now we have:
27.8% of 0.18=0.05004
