To find the whole-to-part ratio for phones and televisions, you first need to determine the total number of phones and televisions sold, and then express the ratio of that total to the total of the two categories.
- Total number of phones sold = 23
- Total number of televisions sold = 17
Now, add these two amounts together to find the total:
Total (phones + televisions) = 23 + 17 = 40
Now, we look at the totals in terms of the whole to part. The whole is the total number of phones and televisions sold, which is 40, and the total number of items sold (phones + stereos + televisions) is:
Total items sold = 23 + 13 + 17 = 53.
Thus, the whole-to-part ratio (total items sold to phones and televisions) is:
53 to 40.
So the answer is: 53 to 40.
