129.12 is what percent of 222.07 - 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 222.07 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 222.07, so we can write it down as 100%=222.07.
4. We know, that x% equals 129.12 of the output value, so we can write it down as x%=129.12.
5. Now we have two simple equations:
1) 100%=222.07
2) x%=129.12
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%=222.07/129.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 129.12 is what percent of 222.07

100%/x%=222.07/129.12
(100/x)*x=(222.07/129.12)*x       - we multiply both sides of the equation by x
100=1.7198729863693*x       - we divide both sides of the equation by (1.7198729863693) to get x
100/1.7198729863693=x
58.143828522538=x
x=58.143828522538

now we have:
129.12 is 58.143828522538% of 222.07
