The correct response is: no, because the ratio of rainy days to sunny days is 2:8 and 1:4 is not equivalent to 2:8.
Here's the explanation:
Out of the 10 days, if it rains for 2 days, there are 8 sunny days (10 days - 2 rainy days = 8 sunny days). Therefore, the ratio of rainy days to sunny days is 2:8, which simplifies to 1:4.
The manager's statement that the ratio of rainy days to sunny days is 1:4 is indeed correct, but the concern raised in the answer choice is incorrect because the simplified ratio 1:4 does match the ratio of rainy days to sunny days, which is 2:8.
Therefore, while the manager's ratio is correct, the phrasing of the remaining options suggests a misunderstanding of the equivalence of the ratios. The critical aspect here is that the ratios are equivalent, so a more accurate phrasing would affirm the manager's statement as correct.
