Answer:
C - 100% of 0.25
Step-by-step explanation:
This answer is basically the same as 25% of 100, just worded differently to confuse you.
25 is 1/4th of 100, so this should be the answer. :)
If you're curious of what the other answers amount to:
One hundredth of 250 = 2.5
50% of 5 = 2.5
40% of 1 = 0.4
We haven n! = (n-1)! x n and (n+1)! = n! x (n + 1);
Then, (n!)^2 = n! x n! = n! x (n-1)! x n;
And (n+1)!(n-1)! = n! x (n + 1) x (n-1)!;
Finally, [n! x (n-1)! x n] / [n! x (n + 1) x (n-1)!] = (n+1)/n;
