74 is what percent of 137.5 - 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 137.5 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 137.5, so we can write it down as 100%=137.5.
4. We know, that x% equals 74 of the output value, so we can write it down as x%=74.
5. Now we have two simple equations:
1) 100%=137.5
2) x%=74
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%=137.5/74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74 is what percent of 137.5

100%/x%=137.5/74
(100/x)*x=(137.5/74)*x       - we multiply both sides of the equation by x
100=1.8581081081081*x       - we divide both sides of the equation by (1.8581081081081) to get x
100/1.8581081081081=x
53.818181818182=x
x=53.818181818182

now we have:
74 is 53.818181818182% of 137.5
