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

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

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

\(\dfrac{70}{90}=\dfrac{70:10}{90:10}=\dfrac{7}{9}\)

= 9/7

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

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

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

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

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

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

học tốt nha :3

70/42=5/3

24/36=2/3

40/70=4/7

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

\(\frac{24}{36}=\frac{24:12}{36:12}=\frac{2}{3}\)

\(\frac{70}{42}=\frac{70:14}{42:14}=\frac{5}{3}\)

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

\(\frac{24}{36}=\frac{24:12}{36:12}=\frac{2}{3}\)

\(\frac{70}{42}=\frac{70:14}{42:14}=\frac{5}{3}\)

\(\frac{60}{72}=\frac{60:12}{72:12}=\frac{5}{6}\)

\(\frac{70}{95}=\frac{70:5}{95:5}=\frac{14}{19}\)

\(\frac{150}{360}=\frac{150:30}{360:30}=\frac{5}{12}\)

 60 / 72 = 5/6

70/95 = 14/19 

150/360 = 5/12 

\(\frac{60}{72}=\frac{60\div12}{72\div12}=\frac{5}{6}\)

\(\frac{70}{95}=\frac{70\div5}{95\div5}=\frac{14}{19}\)

\(\frac{150}{360}=\frac{150\div30}{360\div30}=\frac{5}{12}\)
