I’ve answered this question before. You may find it here:

PrepSwift Tickbox Quiz #2, Question 19

3.625 = 3 + \frac{625}{1000} = 3 + \frac 58. In this case, the remainder would be 5. However, we could rewrite this as: 3 + \frac{5n}{8n} for n in \mathbb{Z} hence any multiple of 5 would work. I think that’s what the question is going for.
