What is 120.9 percent of 55 - 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 55 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 55 is 100%, so we can write it down as 55=100%.
4. We know, that x is 120.9% of the output value, so we can write it down as x=120.9%.
5. Now we have two simple equations:
1) 55=100%
2) x=120.9%
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:
55/x=100%/120.9%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 120.9% of 55

55/x=100/120.9
(55/x)*x=(100/120.9)*x       - we multiply both sides of the equation by x
55=0.82712985938792*x       - we divide both sides of the equation by (0.82712985938792) to get x
55/0.82712985938792=x
66.495=x
x=66.495

now we have:
120.9% of 55=66.495
