395.4 is what percent of 620.44 - 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 620.44 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 620.44, so we can write it down as 100%=620.44.
4. We know, that x% equals 395.4 of the output value, so we can write it down as x%=395.4.
5. Now we have two simple equations:
1) 100%=620.44
2) x%=395.4
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%=620.44/395.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 395.4 is what percent of 620.44

100%/x%=620.44/395.4
(100/x)*x=(620.44/395.4)*x       - we multiply both sides of the equation by x
100=1.5691451694487*x       - we divide both sides of the equation by (1.5691451694487) to get x
100/1.5691451694487=x
63.728966539875=x
x=63.728966539875

now we have:
395.4 is 63.728966539875% of 620.44
