To determine which statement is true about the set of apples and donuts, we need to analyze the provided ratios.
Let's analyze the options given the information:
-
Statement A: The ratio of donuts to apples is 1:2.
- This means for every 1 donut, there are 2 apples. If we have 4 apples, then this means we would have 2 donuts, which matches a 1:2 ratio.
-
Statement B: The ratio of apples to all items is 5:9.
- To check this, the total number of items should be the sum of apples and donuts. If there are 4 apples and 5 donuts, then total items = 4 + 5 = 9. The ratio would then be 4 apples to 9 total items, which is not 5.
-
Statement C: The ratio of donuts to all items is 4:9.
- If there are 5 donuts and 9 total items, the ratio would be 5 donuts to 9 total items, which does not match a 4:9 ratio.
-
Statement D: The ratio of apples to donuts is 4:5.
- If we have 4 apples and 5 donuts, the ratio is indeed 4:5.
Given this analysis:
- Statement A: Might be true, but not confirmed without knowing the exact number of donuts.
- Statement B: False
- Statement C: False
- Statement D: True
Thus, the true statement about the apples and donuts is D: The ratio of apples to donuts is 4:5.
