hai bạn trả lời rồi nên mk ko ghi lại nữa, bài của ten bi mat và Nguyênx Trường Giang đúng rồi đó Trang! :)

a: 90/126=5/7<6/7

b: 70/84=5/6

35/42=5/6

=>70/84=35/42

a)\(\dfrac{90}{126}=\dfrac{5}{7}< \dfrac{6}{7}\Leftrightarrow\cdot\dfrac{90}{126}< \dfrac{6}{7}\)

b)\(\dfrac{70}{84}=\dfrac{5}{6};\dfrac{35}{42}=\dfrac{5}{6}\Leftrightarrow\cdot\dfrac{70}{84}=\dfrac{35}{42}\)

\(a) \frac{1}{4};\frac{3}{7};\frac{101}{131}\)

\(15\div\frac{15}{45}\div15=\frac{1}{3}\)
 

\(\frac{72}{90}=72\div\frac{18}{90}\div18=\frac{4}{5}\)
 

\(50\div\frac{10}{120}\div10=\frac{5}{12}\)

1000000000000% đúng nha

a . 21/70 = 3/10 ; 56/96 = 7/12 ; 60/72 = 15/18

Mình chỉ làm tới đây thôi .
