Answer: They would be A.

Step-by-step explanation: Don't take my word for it 100%

The missing frequencies for G# and D# in the given equal temperament octave is 311.1 and 415.3 respectively. The ratios of frequencies between G# and D# is 1.33.

What is an equal temperament octave?

The equal tempered scale is the common musical scale used at present, used for the tuning of pianos and other instruments of relatively fixed scale. It divides the octave into 12 equal semitones. The ratio between successive notes is constant and it is 1.0595.

With reference to the image attached in the question,

Since we know that ratio between successive notes is 1.0595.

This implies,

[tex]\frac{C\#}{C} = \frac{277.2}{261.6} = 1.0595\\\\[/tex]

Or we can say that, C# = 1.0595C

Similarly,

D# = 1.0595D = 1.0595 * 293.6 = 311.1

G# = 1.0595G = 1.0595 * 392 = 415.3

The ratios of frequencies between G# and D# = [tex]\frac{G\#}{D\#} = \frac{415.3}{311.1} = 1.33 = \frac{4}{3}[/tex]
