What is 50 percent of 200.129 - 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 200.129 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 200.129 is 100%, so we can write it down as 200.129=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) 200.129=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:
200.129/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 200.129

200.129/x=100/50
(200.129/x)*x=(100/50)*x       - we multiply both sides of the equation by x
200.129=2*x       - we divide both sides of the equation by (2) to get x
200.129/2=x
100.0645=x
x=100.0645

now we have:
50% of 200.129=100.0645
