To find the part-to-part ratio for phones to televisions, we take the number of phones sold and the number of televisions sold.
The number of phones sold is 23 and the number of televisions sold is 17.
So, the part-to-part ratio of phones to televisions can be expressed as:
\[ \frac{23}{17} \]
From your options, the correct answer is:
