19.65 is what percent of 57 - 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 57 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 57, so we can write it down as 100%=57.
4. We know, that x% equals 19.65 of the output value, so we can write it down as x%=19.65.
5. Now we have two simple equations:
1) 100%=57
2) x%=19.65
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%=57/19.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.65 is what percent of 57

100%/x%=57/19.65
(100/x)*x=(57/19.65)*x       - we multiply both sides of the equation by x
100=2.9007633587786*x       - we divide both sides of the equation by (2.9007633587786) to get x
100/2.9007633587786=x
34.473684210526=x
x=34.473684210526

now we have:
19.65 is 34.473684210526% of 57
