19.26 is what percent of 25 - 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 25 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 25, so we can write it down as 100%=25.
4. We know, that x% equals 19.26 of the output value, so we can write it down as x%=19.26.
5. Now we have two simple equations:
1) 100%=25
2) x%=19.26
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%=25/19.26
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.26 is what percent of 25

100%/x%=25/19.26
(100/x)*x=(25/19.26)*x       - we multiply both sides of the equation by x
100=1.2980269989616*x       - we divide both sides of the equation by (1.2980269989616) to get x
100/1.2980269989616=x
77.04=x
x=77.04

now we have:
19.26 is 77.04% of 25
