PLEASE HELP!!

Answer 1

1.) the ratio of the note A to middle C = 440.0 / 261.6 = 1.6820 ≈ 1.6818

2.) the ratio of the note D to middle C = 293.7 / 261.6 = 1.1227

3.) D# = 293.6 x 1.0595 = 311.1

4.) the ratio of the frequency of G to C is 1 : 262/392 = 1 : 0.6683 ≈ 3 : 2

5.) the ratio of the frequency of E to C = 1 : 262/330 = 1 : 0.7939 ≈ 5 : 4

6.) The component in a musical note is referred to as the pitch of a sound is the frequency.
