Hok tốt

18/27=2/3

24/32=3/4

15/25=3/5

2/3 , 3/4 , 3/5

\(\frac{35}{42}=\frac{5}{6}\)

\(\frac{54}{24}=\frac{9}{4}\)

\(\frac{18}{6}=\frac{3}{1}=3\)

a) \(\dfrac{8}{16}=\dfrac{8:8}{16:8}=\dfrac{1}{2}\)

b) \(\dfrac{10}{30}=\dfrac{10:10}{30:10}=\dfrac{1}{3}\)

c) \(\dfrac{24}{18}=\dfrac{24:6}{18:6}=\dfrac{4}{3}\)

d) \(\dfrac{20}{28}=\dfrac{20:4}{28:4}=\dfrac{5}{7}\)

Rút gọn các phân số: a) 2 10 b) 9 6 c) 5 20 d) 6 16 Hướng dẫn giải a) 2 10 = 2 : 2 10 : 2 = 1 5 b) 9 6 = 9 : 3 6 : 3 = 3 2 c) 5 20 = 5 : 5 20 : 5 = 1 4 d) 6 16 = 6 : 2 16 : 2 = 3 8

Hơi bị lỗi, thông cảm.

Theo thứ tự : 5/6 ; 2/3 ; 2/3 ; 3/2 ; 2/3 ; 3/8 ; 3/1(hay là 3)

\(\dfrac{10}{12}=\dfrac{5}{6}\)        \(\dfrac{8}{12}=\dfrac{2}{3}\)        \(\dfrac{10}{15}=\dfrac{2}{3}\)        \(\dfrac{27}{18}=\dfrac{3}{2}\)        \(\dfrac{24}{36}=\dfrac{4}{6}=\dfrac{2}{3}\)

\(\dfrac{18}{48}=\dfrac{3}{8}\)        \(\dfrac{42}{14}=\dfrac{6}{2}=\dfrac{3}{1}\)

12/18=2/3 [rút gọn cho 6]

4/40=1/10 [rút gọn cho 4]

18/24=3/4 [rút gọn cho 6]

20/35=4/7 [rút gọn cho 5]

60/12=5

các đáp án đây nhé!

12/18 =  2/3

 4/40=1/10

18/24 =3/4

20/35=4/7

60/12=5/1=5

5/7>6/21

18/24>15/25

12/13=1212/1313

\(\dfrac{5}{7}\)>\(\dfrac{6}{21}\)

\(\dfrac{18}{24}\)>\(\dfrac{15}{25}\)

\(\dfrac{12}{13}\)=\(\dfrac{1212}{1313}\)

18/24=3/4

36/27=4/3

vì 4/3>1

   3/4<1

nên 3/4<4/3

18/24=3/4

36/27=4/3

vi3/4<1 vaf/3>1

suy ra 3/4<4/3
