321.77 is what percent of 805 - 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 805 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 805, so we can write it down as 100%=805.
4. We know, that x% equals 321.77 of the output value, so we can write it down as x%=321.77.
5. Now we have two simple equations:
1) 100%=805
2) x%=321.77
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%=805/321.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.77 is what percent of 805

100%/x%=805/321.77
(100/x)*x=(805/321.77)*x       - we multiply both sides of the equation by x
100=2.5017869907076*x       - we divide both sides of the equation by (2.5017869907076) to get x
100/2.5017869907076=x
39.971428571429=x
x=39.971428571429

now we have:
321.77 is 39.971428571429% of 805
