19.26 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
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%=30
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%=30/19.26
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 30

100%/x%=30/19.26
(100/x)*x=(30/19.26)*x       - we multiply both sides of the equation by x
100=1.5576323987539*x       - we divide both sides of the equation by (1.5576323987539) to get x
100/1.5576323987539=x
64.2=x
x=64.2

now we have:
19.26 is 64.2% of 30
