What is 50 percent of 278200 - 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 278200 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 278200 is 100%, so we can write it down as 278200=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) 278200=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:
278200/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 278200

278200/x=100/50
(278200/x)*x=(100/50)*x       - we multiply both sides of the equation by x
278200=2*x       - we divide both sides of the equation by (2) to get x
278200/2=x
139100=x
x=139100

now we have:
50% of 278200=139100
