12.5 is what percent of 54.99 - 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 54.99 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 54.99, so we can write it down as 100%=54.99.
4. We know, that x% equals 12.5 of the output value, so we can write it down as x%=12.5.
5. Now we have two simple equations:
1) 100%=54.99
2) x%=12.5
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%=54.99/12.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.5 is what percent of 54.99

100%/x%=54.99/12.5
(100/x)*x=(54.99/12.5)*x       - we multiply both sides of the equation by x
100=4.3992*x       - we divide both sides of the equation by (4.3992) to get x
100/4.3992=x
22.731405710129=x
x=22.731405710129

now we have:
12.5 is 22.731405710129% of 54.99
