Question

so sánh qua số trung gian 4/17 và 16/63,5/29 và 7/33,44/57 và 89/99,19/53 và 30/73 9 giải ( chi tiết 1 câu hộ mình nhé)

 

Answer 1

\(\dfrac{4}{7}v\text{à }\dfrac{16}{63}\\ \dfrac{4}{7}=\dfrac{4\cdot9}{7\cdot9}=\dfrac{36}{63}\\ \dfrac{36}{63}>\dfrac{16}{63}\\ \Rightarrow\dfrac{4}{7}>\dfrac{16}{36}\) 

Answer 2

\(\dfrac{4}{17}\) và \(\dfrac{16}{63}\)

\(\dfrac{4}{63}>\dfrac{16}{63}\)

\(=>\dfrac{4}{17}>\dfrac{16}{63}\)

\(\dfrac{5}{29}\) và \(\dfrac{7}{33}\)

\(\dfrac{5}{33}< \dfrac{7}{33}\)

\(=>\dfrac{5}{29}< \dfrac{7}{33}\)

\(\dfrac{44}{57}\) và \(\dfrac{89}{99}\)

\(\dfrac{44}{99}< \dfrac{89}{99}\)

\(=>\dfrac{44}{57}< \dfrac{89}{99}\)

\(\dfrac{19}{53}\) và \(\dfrac{30}{73}\)

\(\dfrac{19}{73}>\dfrac{30}{73}\)

\(=>\dfrac{19}{53}>\dfrac{30}{73}\)

Answer 3

Ta có:

4/17<4/16=1/4

16/63>16/64=1/4

Do 4/17<1/4<16/63 

Nên 16/63>4/17
