0.5 is what percent of 21.46 - 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 21.46 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 21.46, so we can write it down as 100%=21.46.
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%=21.46
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%=21.46/0.5
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 21.46

100%/x%=21.46/0.5
(100/x)*x=(21.46/0.5)*x       - we multiply both sides of the equation by x
100=42.92*x       - we divide both sides of the equation by (42.92) to get x
100/42.92=x
2.3299161230196=x
x=2.3299161230196

now we have:
0.5 is 2.3299161230196% of 21.46
