Final answer:
To find out what fraction of rams is left, subtract the fraction sold from the fraction remaining after the cold. The calculation yields 2/5, which isn't listed in the options, possibly due to a mistake in the question.
Step-by-step explanation:
If Jose initially had a certain number of rams and now only has 18/25 of them due to the cold, and he has sold 8/25 of the initial quantity, to find the fraction of rams left, we subtract the fraction sold from the fraction he has left after accounting for the cold. This gives us 18/25 - 8/25 = 10/25, which is equal to 2/5 when simplified. However, since this fraction is not one of the answer options provided, it seems there might be a typo or misunderstanding in the formulation of the question. If we assume the answer must be one of the given choices, then the closest answer to our calculation would be 9/25.
