What is 15.72 percent of 30400 - 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 30400 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 30400 is 100%, so we can write it down as 30400=100%.
4. We know, that x is 15.72% of the output value, so we can write it down as x=15.72%.
5. Now we have two simple equations:
1) 30400=100%
2) x=15.72%
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:
30400/x=100%/15.72%
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 15.72% of 30400

30400/x=100/15.72
(30400/x)*x=(100/15.72)*x       - we multiply both sides of the equation by x
30400=6.3613231552163*x       - we divide both sides of the equation by (6.3613231552163) to get x
30400/6.3613231552163=x
4778.88=x
x=4778.88

now we have:
15.72% of 30400=4778.88
