It would be 16/7, or 2 2/7 as a mixed number. Correct me if i'm wrong :)
By subtract this problem, I got answer C .44.22.Right?
If it is divisible by 3 and 7 then it is divisible by (3 times 7)
3 time s7=21
just do muliplyes of 21 and find which are between 364 and 384
21
42
63
...
336
357
378
399
answer is 378
