42.5 is what percent of 67 - 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 67 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 67, so we can write it down as 100%=67.
4. We know, that x% equals 42.5 of the output value, so we can write it down as x%=42.5.
5. Now we have two simple equations:
1) 100%=67
2) x%=42.5
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%=67/42.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.5 is what percent of 67

100%/x%=67/42.5
(100/x)*x=(67/42.5)*x       - we multiply both sides of the equation by x
100=1.5764705882353*x       - we divide both sides of the equation by (1.5764705882353) to get x
100/1.5764705882353=x
63.432835820896=x
x=63.432835820896

now we have:
42.5 is 63.432835820896% of 67
