122.9 is what percent of 132 - 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 132 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 132, so we can write it down as 100%=132.
4. We know, that x% equals 122.9 of the output value, so we can write it down as x%=122.9.
5. Now we have two simple equations:
1) 100%=132
2) x%=122.9
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%=132/122.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 122.9 is what percent of 132

100%/x%=132/122.9
(100/x)*x=(132/122.9)*x       - we multiply both sides of the equation by x
100=1.0740439381611*x       - we divide both sides of the equation by (1.0740439381611) to get x
100/1.0740439381611=x
93.106060606061=x
x=93.106060606061

now we have:
122.9 is 93.106060606061% of 132
