4.1 is what percent of 0.5 - 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 0.5 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 0.5, so we can write it down as 100%=0.5.
4. We know, that x% equals 4.1 of the output value, so we can write it down as x%=4.1.
5. Now we have two simple equations:
1) 100%=0.5
2) x%=4.1
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%=0.5/4.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.1 is what percent of 0.5

100%/x%=0.5/4.1
(100/x)*x=(0.5/4.1)*x       - we multiply both sides of the equation by x
100=0.1219512195122*x       - we divide both sides of the equation by (0.1219512195122) to get x
100/0.1219512195122=x
820=x
x=820

now we have:
4.1 is 820% of 0.5
