I must be doing this wrong

Doing the first line too me about 15 minutes, and I'm not even sure if I'm doing it right. All the previous assignments in this class took around 15 minutes total to complete, this one seems like it's taking too long and I'm getting the wrong answer in the end.

Here are my answers for the first line, if anyone can tell me if I'm correct/incorrect and what I could possibly be doing wrong, it would be greatly appreciated:

The first value is the interval of the two notes, the second value is the inverse of the first interval, the third value is the new note corresponding to the inverted interval.

1. P4, P5, C
2. M6, m3, G
3. M6, m3, B
4. d4, A5, G
5. m7, M2, B
6. d5, A4, B#

What I have been doing:
Counting how many letter's change, writing that number down. Then counting the half-steps between the two notes. That gets me the interval.

Inverting the interval is easy.

Finding the new note, I count up that many letters, write down that note. Then I count half steps and add any sharps or flats.

How can you have multiple whole notes in the same bar? Is this piano?

I do not know. I am an Electrical Engineering major and I have never played an instrument. The only reason I'm taking this class is to satisfy my GE requirements.

The first interval is not a perfect fourth, you are going from F to B. That is a half step more than a fourth. Probably go for d5, although I'm not very knowledgable about music theory. So the inverted chord would also be a d5, but with B as the root.

Yeah, the first one is really an Augmented 4th.

1. A4, d5, B

4. d5, M6, M6, M3, m7, d5
5. M3, M7, m2, m6, M3, M2
6. M3, P5, M7, m6, d5, M7

when doing an inversion, make both your numbers add up to 9, and then pair up M and m, d and A, (for example, the inverse of a m7 is a M2)
