What is 72.38 percent of 15.78 - 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 15.78 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 15.78 is 100%, so we can write it down as 15.78=100%.
4. We know, that x is 72.38% of the output value, so we can write it down as x=72.38%.
5. Now we have two simple equations:
1) 15.78=100%
2) x=72.38%
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:
15.78/x=100%/72.38%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 72.38% of 15.78

15.78/x=100/72.38
(15.78/x)*x=(100/72.38)*x       - we multiply both sides of the equation by x
15.78=1.381597126278*x       - we divide both sides of the equation by (1.381597126278) to get x
15.78/1.381597126278=x
11.421564=x
x=11.421564

now we have:
72.38% of 15.78=11.421564
