Answer 4

B=196+197/197+198=196/197+198+197/197+198

=>196/197>196/197+198

=>197/198>197?197+198

Vậy A>B

Answer 5

\(A=\frac{196}{197}+\frac{197}{198}\) ; \(B=196+\frac{197}{197}+198\)

Ta có : \(\frac{196}{197}+\frac{197}{198}=1,989873.......\)

\(196+\frac{197}{197}+198=196+1+198=395\)

=> \(A>B\)

Answer 6

A > B

Answer 7

\(A=\frac{196}{197}+\frac{197}{198}=\frac{196.198+197.197}{197.198}>1\)

\(B=\frac{196+197}{197+198}=\frac{393}{395}< 1\)

\(\Rightarrow A>B\)
