42.5 is what percent of 72.75 - 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 72.75 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 72.75, so we can write it down as 100%=72.75.
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%=72.75
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%=72.75/42.5
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 72.75

100%/x%=72.75/42.5
(100/x)*x=(72.75/42.5)*x       - we multiply both sides of the equation by x
100=1.7117647058824*x       - we divide both sides of the equation by (1.7117647058824) to get x
100/1.7117647058824=x
58.419243986254=x
x=58.419243986254

now we have:
42.5 is 58.419243986254% of 72.75
