To evaluate the statements, we can find the ratios based on the information given: there are 5 donuts and 4 apples.
-
Donuts to Apples:
- The ratio of donuts (5) to apples (4) is \( 5:4 \).
- Therefore, Statement A ("The ratio of donuts to apples is 1:2") is False.
-
Apples to All Items:
- Total items = donuts + apples = 5 + 4 = 9.
- The ratio of apples (4) to total items (9) is \( 4:9 \).
- Therefore, Statement B ("The ratio of apples to all items is 5:9") is False.
-
Donuts to All Items:
- The ratio of donuts (5) to total items (9) is \( 5:9 \).
- Therefore, Statement C ("The ratio of donuts to all items is 4:9") is False.
-
Apples to Donuts:
- The ratio of apples (4) to donuts (5) is \( 4:5 \).
- Therefore, Statement D ("The ratio of apples to donuts is 4:5") is True.
Thus, the correct statement is D: The ratio of apples to donuts is 4:5.
