12.77 is what percent of 22 - 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 22 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 22, so we can write it down as 100%=22.
4. We know, that x% equals 12.77 of the output value, so we can write it down as x%=12.77.
5. Now we have two simple equations:
1) 100%=22
2) x%=12.77
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%=22/12.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.77 is what percent of 22

100%/x%=22/12.77
(100/x)*x=(22/12.77)*x       - we multiply both sides of the equation by x
100=1.7227877838684*x       - we divide both sides of the equation by (1.7227877838684) to get x
100/1.7227877838684=x
58.045454545455=x
x=58.045454545455

now we have:
12.77 is 58.045454545455% of 22
