Question

 

Answer 1

e) \(\dfrac{67}{77}=\dfrac{5561}{6391};\dfrac{73}{83}=\dfrac{5621}{6391}\)

vì 5561 < 5621 nên \(\dfrac{67}{77}< \dfrac{73}{83}\)

f) \(\dfrac{11}{32}=\dfrac{539}{1568};\dfrac{16}{49}=\dfrac{512}{1568}\)

vì 539 > 512 nên \(\dfrac{11}{32}>\dfrac{16}{49}\)

Answer 2

e: 67/77=1-10/77

73/83=1-10/83

mà 10/77>10/83

nên 67/77<73/83

b: 11/32>11/33=1/3

1/3=16/48>16/49

=>11/32>16/49
