1000000000000% đúng nha
Bài 1:
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
c: 5/25=1/5
75/100=3/4
64/720=4/45
16/1000=2/125
Bài 2:
Các phân số bằng 2/3 là 34/51; 20/30; 84/126
Bài 1 :
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
c) 5 / 25 = 1/5 ; 75/100=3/4 ; 64/720=4/45 ; 16/1000=2/125
Bài 2 :
Các phân số bằng 2/3 là :
\(\text{34/51; 20/30; 84/126}\)
11/12=1/2 , 36/10=18/5 , 75/36 = 25/12 , 14/28 = 1/2 , 48/30 = 8/5
\(\dfrac{48}{78}=\dfrac{48:6}{78:6}=\dfrac{8}{13}\)
\(\dfrac{39}{75}=\dfrac{39:3}{75:3}=\dfrac{13}{25}\)
\(\dfrac{120}{90}=\dfrac{120:30}{90:30}=\dfrac{4}{3}\)
`48/78 = 8/13`
`39/75 =13/25`
`120/90 =4/3`
