18.77 is what percent of 27.5 - 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 27.5 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 27.5, so we can write it down as 100%=27.5.
4. We know, that x% equals 18.77 of the output value, so we can write it down as x%=18.77.
5. Now we have two simple equations:
1) 100%=27.5
2) x%=18.77
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%=27.5/18.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.77 is what percent of 27.5

100%/x%=27.5/18.77
(100/x)*x=(27.5/18.77)*x       - we multiply both sides of the equation by x
100=1.4651038891849*x       - we divide both sides of the equation by (1.4651038891849) to get x
100/1.4651038891849=x
68.254545454545=x
x=68.254545454545

now we have:
18.77 is 68.254545454545% of 27.5
