The 5 of B♭ is F
The 5 (five) of B♭ (B flat, Bb) is F: a perfect fifth above the root.
B♭ — the root, 1F — the 5
How to find it
Count letters first, the root included: B, C, D, E, F. A 5th lands on F.
Then the sound: a perfect fifth is 7 semitones above B♭, which is exactly where F is — no sharp or flat needed.
