What is 2.7 percent of 20.55 - 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 20.55 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 20.55 is 100%, so we can write it down as 20.55=100%.
4. We know, that x is 2.7% of the output value, so we can write it down as x=2.7%.
5. Now we have two simple equations:
1) 20.55=100%
2) x=2.7%
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:
20.55/x=100%/2.7%
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 2.7% of 20.55

20.55/x=100/2.7
(20.55/x)*x=(100/2.7)*x       - we multiply both sides of the equation by x
20.55=37.037037037037*x       - we divide both sides of the equation by (37.037037037037) to get x
20.55/37.037037037037=x
0.55485=x
x=0.55485

now we have:
2.7% of 20.55=0.55485
