What is 50.75 percent of 840 - 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 840 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 840 is 100%, so we can write it down as 840=100%.
4. We know, that x is 50.75% of the output value, so we can write it down as x=50.75%.
5. Now we have two simple equations:
1) 840=100%
2) x=50.75%
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:
840/x=100%/50.75%
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 50.75% of 840

840/x=100/50.75
(840/x)*x=(100/50.75)*x       - we multiply both sides of the equation by x
840=1.9704433497537*x       - we divide both sides of the equation by (1.9704433497537) to get x
840/1.9704433497537=x
426.3=x
x=426.3

now we have:
50.75% of 840=426.3
