Music Math Question, Please Help!

[leavesaregreen52]

I can't figure this out at all because I keep getting answers that aren't matching up. Could someone help me?

Calculate the Fundamental Frequency Ratio (by dividing the higher frequency by the lower
frequency), rounded if necessary to the nearest 0.000001, between D4 and G#4 under the following systems:
a) Harmonic Series (Keyed to A)
b) Just Intonation Tuning (Keyed to A)
c) Harmonic Series (Keyed to D)
d) Pythagorean Tuning

3) In your answers to 2, consider the answer 2c what you want (in other words, zero error). Calculate the error, as a percent, for each of these tuning systems in parts a, b, and d. Round to the nearest 0.001%.

We'd love to help, but to do that we need to know where you need help (and where you don't).

Please show us at least one attempt, so we can see where you are right, and where you are wrong.

In particular, we'll want to see the definitions you are using for the four sequences, including any specific frequencies you are using.
