0.18 is what percent of 0.47 - 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 0.47 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 0.47, so we can write it down as 100%=0.47.
4. We know, that x% equals 0.18 of the output value, so we can write it down as x%=0.18.
5. Now we have two simple equations:
1) 100%=0.47
2) x%=0.18
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%=0.47/0.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.18 is what percent of 0.47

100%/x%=0.47/0.18
(100/x)*x=(0.47/0.18)*x       - we multiply both sides of the equation by x
100=2.6111111111111*x       - we divide both sides of the equation by (2.6111111111111) to get x
100/2.6111111111111=x
38.297872340426=x
x=38.297872340426

now we have:
0.18 is 38.297872340426% of 0.47
