What is 50.9 percent of 30.917 - 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 30.917 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 30.917 is 100%, so we can write it down as 30.917=100%.
4. We know, that x is 50.9% of the output value, so we can write it down as x=50.9%.
5. Now we have two simple equations:
1) 30.917=100%
2) x=50.9%
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:
30.917/x=100%/50.9%
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 50.9% of 30.917

30.917/x=100/50.9
(30.917/x)*x=(100/50.9)*x       - we multiply both sides of the equation by x
30.917=1.9646365422397*x       - we divide both sides of the equation by (1.9646365422397) to get x
30.917/1.9646365422397=x
15.736753=x
x=15.736753

now we have:
50.9% of 30.917=15.736753
