6/10=3/5

70/90=7/9

96/72=4/3

45/35=9/7 nha

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

\(\dfrac{70}{74}\) = \(\dfrac{35}{37}\)

\(\dfrac{70}{74}=\dfrac{35\cdot2}{37\cdot2}=\dfrac{35}{37}\)

\(\dfrac{70}{74}\)=\(\dfrac{70:2}{74:2}\)=\(\dfrac{35}{37}\)

50>5;70>7=5/7

50/70 = 5/7

\(\frac{50}{70}=\frac{5}{7}\)

40/70

=40:10/70:10

=4/7

Đáp số: 4/7

dm máy tính đâu

\(\frac{40}{70}=\frac{40:10}{70:10}=\frac{4}{7}\)

\(\frac{301}{70}=\frac{301:7}{70:7}=\frac{43}{10}\)

.....................

........................

Ta có:

\(\frac{301}{70}\)= \(\frac{43}{10}\)

Đề bài: Rút gọn phân số \(\frac{301}{70}\)

Ta có: \(\frac{301}{70}=\frac{301\div7}{70\div7}=\frac{43}{10}\)

Vậy: \(\frac{301}{70}\)rút gọn thành\(\frac{43}{10}\)

\(\dfrac{50}{70}=\dfrac{50:10}{70:10}=\dfrac{5}{7}\)
\(\dfrac{24}{120}=\dfrac{24:24}{120:24}=\dfrac{1}{5}\)

\(\dfrac{50}{70}=\dfrac{5}{7}\\ \dfrac{24}{120}=\dfrac{1}{5}\)

50/70=50:10/70:10=5/7

24/120=24:24/120:24=1/5 

\(\frac{70}{95}=\frac{15}{19}\)

70/95=14/19

\(\frac{70}{95}\)=\(\frac{14}{19}\)
