393.8 is what percent of 2475 - 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 2475 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 2475, so we can write it down as 100%=2475.
4. We know, that x% equals 393.8 of the output value, so we can write it down as x%=393.8.
5. Now we have two simple equations:
1) 100%=2475
2) x%=393.8
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%=2475/393.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 393.8 is what percent of 2475

100%/x%=2475/393.8
(100/x)*x=(2475/393.8)*x       - we multiply both sides of the equation by x
100=6.2849162011173*x       - we divide both sides of the equation by (6.2849162011173) to get x
100/6.2849162011173=x
15.911111111111=x
x=15.911111111111

now we have:
393.8 is 15.911111111111% of 2475
