57.75 is what percent of 800 - 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 800 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 100% equals 800, so we can write it down as 100%=800.
4. We know, that x% equals 57.75 of the output value, so we can write it down as x%=57.75.
5. Now we have two simple equations:
1) 100%=800
2) x%=57.75
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:
100%/x%=800/57.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.75 is what percent of 800

100%/x%=800/57.75
(100/x)*x=(800/57.75)*x       - we multiply both sides of the equation by x
100=13.852813852814*x       - we divide both sides of the equation by (13.852813852814) to get x
100/13.852813852814=x
7.21875=x
x=7.21875

now we have:
57.75 is 7.21875% of 800
