Question

A minor chord is composed of notes whole frequencies are in the
ratio 10:12:15 If the first note of a minor chord is A with a
frequency of 220 Hertz, what are the frequencies of the other 2
notes?

Dear Student,
The ratio of the frequencies in theory are
10:12:15

thus the ratio of the true frequency should be 220:X:Y

Calculations:

220/10 = X/12 = Y/15

Calculate the value of X separately by:

220/10 = X/12

thus: X = (220/10) * 12 = 264
Similarly calculate y
