15.25 is what percent of 19.09 - 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 19.09 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 19.09, so we can write it down as 100%=19.09.
4. We know, that x% equals 15.25 of the output value, so we can write it down as x%=15.25.
5. Now we have two simple equations:
1) 100%=19.09
2) x%=15.25
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%=19.09/15.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.25 is what percent of 19.09

100%/x%=19.09/15.25
(100/x)*x=(19.09/15.25)*x       - we multiply both sides of the equation by x
100=1.2518032786885*x       - we divide both sides of the equation by (1.2518032786885) to get x
100/1.2518032786885=x
79.884756416972=x
x=79.884756416972

now we have:
15.25 is 79.884756416972% of 19.09
