What is 30.8 percent of 50.99 - 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 50.99 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 50.99 is 100%, so we can write it down as 50.99=100%.
4. We know, that x is 30.8% of the output value, so we can write it down as x=30.8%.
5. Now we have two simple equations:
1) 50.99=100%
2) x=30.8%
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:
50.99/x=100%/30.8%
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 30.8% of 50.99

50.99/x=100/30.8
(50.99/x)*x=(100/30.8)*x       - we multiply both sides of the equation by x
50.99=3.2467532467532*x       - we divide both sides of the equation by (3.2467532467532) to get x
50.99/3.2467532467532=x
15.70492=x
x=15.70492

now we have:
30.8% of 50.99=15.70492
