What is 50 percent of 16.31 - 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 16.31 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 16.31 is 100%, so we can write it down as 16.31=100%.
4. We know, that x is 50% of the output value, so we can write it down as x=50%.
5. Now we have two simple equations:
1) 16.31=100%
2) x=50%
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:
16.31/x=100%/50%
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% of 16.31

16.31/x=100/50
(16.31/x)*x=(100/50)*x       - we multiply both sides of the equation by x
16.31=2*x       - we divide both sides of the equation by (2) to get x
16.31/2=x
8.155=x
x=8.155

now we have:
50% of 16.31=8.155
