Which digits make 3,71 divisible by 3 a.3 only b.7 only c.1 only d.1,4 and 7

Answer:
D) 1, 4, and 7
Step-by-step explanation:
If you take 600 from the number, you will get 11_. Ignore the 3000 because it's divisible by 3. If you take 90 away from 11_, you will be leftover with 2_.
18 is the closest number to 20 which is divisible by 3.
Count...
21, 24, 27, and 30.
Therefore, your answer will be 1, 4, 7.
