0.27 is what percent of 0.55 - 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 0.55 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 100% equals 0.55, so we can write it down as 100%=0.55.
4. We know, that x% equals 0.27 of the output value, so we can write it down as x%=0.27.
5. Now we have two simple equations:
1) 100%=0.55
2) x%=0.27
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%=0.55/0.27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.27 is what percent of 0.55

100%/x%=0.55/0.27
(100/x)*x=(0.55/0.27)*x       - we multiply both sides of the equation by x
100=2.037037037037*x       - we divide both sides of the equation by (2.037037037037) to get x
100/2.037037037037=x
49.090909090909=x
x=49.090909090909

now we have:
0.27 is 49.090909090909% of 0.55
