0.5 is what percent of 22.1 - 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 22.1 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 22.1, so we can write it down as 100%=22.1.
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%=22.1
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%=22.1/0.5
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 22.1

100%/x%=22.1/0.5
(100/x)*x=(22.1/0.5)*x       - we multiply both sides of the equation by x
100=44.2*x       - we divide both sides of the equation by (44.2) to get x
100/44.2=x
2.262443438914=x
x=2.262443438914

now we have:
0.5 is 2.262443438914% of 22.1
