96/104 = 1 - 8/104
94/102 = 1 - 8/102
Do 102 < 104 ⇒ 8/104 < 8/102
⇒ 1 - 8/104 > 1 - 8/102
Vậy 96/104 > 94/102
Rút gọn ta được:
\(\dfrac{96}{104}=\dfrac{12}{13};\dfrac{94}{102}=\dfrac{47}{51}\)
Quy đồng:
\(\dfrac{12}{13}=\dfrac{612}{663};\dfrac{47}{51}=\dfrac{611}{663}\)
So sánh: \(\dfrac{612}{663}>\dfrac{611}{663}\)
Vậy \(\dfrac{96}{104}>\dfrac{94}{102}\).
