Marvetta,
N directly proportional to S with the formula
N = kS
in case you were asked for inverse it would be N = (1/s) * k = k/S
But we are interested in direct proportion
N = k S
\Question b
You will have to find the value of k to get that gap. The question is only asking for N by providing S
N = k S
N = 2, 000, 000 and S = 25
N = k S will be 2, 000, 000 = k * 25
k = 2, 000, 000 / 25 = 80, 000
If S is given as 180 megahertz
Then N =k S will be N = 80, 000 * 180 = 14, 400, 000
And that fills your gap...
