50 is what percent of 42.25 - 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 42.25 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 42.25, so we can write it down as 100%=42.25.
4. We know, that x% equals 50 of the output value, so we can write it down as x%=50.
5. Now we have two simple equations:
1) 100%=42.25
2) x%=50
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%=42.25/50
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 50 is what percent of 42.25

100%/x%=42.25/50
(100/x)*x=(42.25/50)*x       - we multiply both sides of the equation by x
100=0.845*x       - we divide both sides of the equation by (0.845) to get x
100/0.845=x
118.34319526627=x
x=118.34319526627

now we have:
50 is 118.34319526627% of 42.25
