0.5 is what percent of 3.11 - 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 3.11 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 3.11, so we can write it down as 100%=3.11.
4. We know, that x% equals 0.5 of the output value, so we can write it down as x%=0.5.
5. Now we have two simple equations:
1) 100%=3.11
2) x%=0.5
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%=3.11/0.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.5 is what percent of 3.11

100%/x%=3.11/0.5
(100/x)*x=(3.11/0.5)*x       - we multiply both sides of the equation by x
100=6.22*x       - we divide both sides of the equation by (6.22) to get x
100/6.22=x
16.077170418006=x
x=16.077170418006

now we have:
0.5 is 16.077170418006% of 3.11
