The note A has a frequency of 880 hertz. The note D has a frequency of 1,175 hertz. Find the ratio of D to A to two decimal plac
Trava [24]

Step-by-step explanation:

We have,

The frequency of note A is 880 Hz and the frequency of note D is 1175 Hz. It is required to find the ratio of D to A.

It means \dfrac{f_D}{f_A}.

Using the values of frequency of D and A. So,

\dfrac{f_D}{f_A}=\dfrac{1175}{880}

In decimal form,

\dfrac{f_D}{f_A}=1.33

In integer form,

\dfrac{f_D}{f_A}=\dfrac{1175 }{880}\\\\\dfrac{f_D}{f_A}=\dfrac{235}{176}
