0.5 is what percent of 18.3 - 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 18.3 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 18.3, so we can write it down as 100%=18.3.
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%=18.3
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%=18.3/0.5
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 18.3

100%/x%=18.3/0.5
(100/x)*x=(18.3/0.5)*x       - we multiply both sides of the equation by x
100=36.6*x       - we divide both sides of the equation by (36.6) to get x
100/36.6=x
2.7322404371585=x
x=2.7322404371585

now we have:
0.5 is 2.7322404371585% of 18.3
