Okay so they were both 9, nine years ago because 9 plus 9 is 18.
They would both be 18 in the present age im pretty sure?
A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3
which gives:
x = <span>164.81 </span>× 3 ÷ 2
= 247.21
Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
X= 1.9
Steps:
16.5-9.2=7.3
9.2-7.3=1.9
