137.5 is what percent of 150 - 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 150 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 150, so we can write it down as 100%=150.
4. We know, that x% equals 137.5 of the output value, so we can write it down as x%=137.5.
5. Now we have two simple equations:
1) 100%=150
2) x%=137.5
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%=150/137.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 137.5 is what percent of 150

100%/x%=150/137.5
(100/x)*x=(150/137.5)*x       - we multiply both sides of the equation by x
100=1.0909090909091*x       - we divide both sides of the equation by (1.0909090909091) to get x
100/1.0909090909091=x
91.666666666667=x
x=91.666666666667

now we have:
137.5 is 91.666666666667% of 150
