bạn tk mk nha~~~

18/30=3/5

48/96=1/2

64/720=4/45

42/98=24/49

a)

`6/9=2/3`

`6/24=1/4`

`48/96=1/2`

`42/98=3/7`

b)

`24/36=2/3`

`18/30=3/5`

`15/120=1/8`

`80/240=1/3`

a)\(\dfrac{6}{9}=\dfrac{6:3}{9:3}=\dfrac{2}{3}\)
\(\dfrac{6}{24}=\dfrac{6:6}{24:6}=\dfrac{1}{4}\)
\(\dfrac{48}{96}=\dfrac{48:48}{96:48}=\dfrac{1}{2}\)
\(\dfrac{42}{98}=\dfrac{42:14}{98:14}=\dfrac{3}{7}\)
b)\(\dfrac{24}{36}=\dfrac{24:12}{36:12}=\dfrac{2}{3}\)
\(\dfrac{18}{30}=\dfrac{18:6}{30:6}=\dfrac{3}{5}\)
\(\dfrac{15}{120}=\dfrac{15:15}{120:15}=\dfrac{1}{8}\)
\(\dfrac{80}{240}=\dfrac{80:80}{240:80}=\dfrac{1}{3}\)

\(a,\dfrac{6}{9}=\dfrac{2}{3};\dfrac{6}{24}=\dfrac{1}{4};\dfrac{48}{96}=\dfrac{1}{2};\dfrac{42}{98}=\dfrac{3}{7}\\ b,\dfrac{24}{36}=\dfrac{2}{3};\dfrac{18}{30}=\dfrac{3}{5};\dfrac{15}{120}=\dfrac{1}{8};\dfrac{80}{240}=\dfrac{1}{3}\)

6/9=2/3

6/24=1/4

48/96=1/2

42/98=3/7

2/3 ; 1/4 ; 1/2;3/7 cho **** nha bạn thương

6/9 = 2/3

6/24 = 1/4

48/96 = 1/2

42/98 = 3/7

21/49

3/7

vẫn quá dễ

\(\frac{48}{96}=\frac{48:48}{96:48}=\frac{1}{2}\)

\(\frac{42}{98}=\frac{42:14}{98:14}=\frac{3}{7}\)

\(\frac{80}{240}=\frac{80:80}{240:80}=\frac{1}{3}\)

\(\frac{75}{100}=\frac{75:25}{100:25}=\frac{3}{4}\)

\(\frac{64}{720}=\frac{64:16}{720:16}=\frac{4}{45}\)

\(\frac{15}{120}=\frac{15:15}{120:15}=\frac{1}{8}\)

48/96=1/2

42/98=3/7

80/240=1/3

75/100=3/4

64/720=4/45

15/120=1/8

48/96=1/2

42/98=3/7

80/240=1/3

75/100=3/4

64/720=4/45

15/120=1/8

\(\dfrac{50}{60}=\dfrac{5}{6}\)
\(\dfrac{33}{11}=3\)
\(\dfrac{16}{60}=\dfrac{4}{15}\)
\(\dfrac{42}{22}=\dfrac{21}{11}\)

chia là gì z

50/60=5/6

33/11=3

16/60=4/15

42/22=21/11

HT ☘

`97/98` nó là phân số tối giản nên ko rút gọn dc

Nếu mình không nhầm thì phân số trên đã tối giản rồi ạ 

Ờm thanks bn

30/42=5/7
