0.5 is what percent of 165 - 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 165 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 165, so we can write it down as 100%=165.
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%=165
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%=165/0.5
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 165

100%/x%=165/0.5
(100/x)*x=(165/0.5)*x       - we multiply both sides of the equation by x
100=330*x       - we divide both sides of the equation by (330) to get x
100/330=x
0.3030303030303=x
x=0.3030303030303

now we have:
0.5 is 0.3030303030303% of 165
