132.5 is what percent of 121.9 - 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 121.9 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 121.9, so we can write it down as 100%=121.9.
4. We know, that x% equals 132.5 of the output value, so we can write it down as x%=132.5.
5. Now we have two simple equations:
1) 100%=121.9
2) x%=132.5
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%=121.9/132.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 132.5 is what percent of 121.9

100%/x%=121.9/132.5
(100/x)*x=(121.9/132.5)*x       - we multiply both sides of the equation by x
100=0.92*x       - we divide both sides of the equation by (0.92) to get x
100/0.92=x
108.69565217391=x
x=108.69565217391

now we have:
132.5 is 108.69565217391% of 121.9
