a) 5 : 8 = $\frac{5}{8}$     ;     11 : 15 = $\frac{{11}}{{15}}$                                                               

4 : 8 = $\frac{4}{8}$   ;    $1:2 = \frac{1}{2}$

a) 7 : 6 = $\frac{7}{6}$     ;     3 : 2 = $\frac{3}{2}$           

 $9:9 = \frac{9}{9}$   ;    $16:1 = \frac{{16}}{1}$

a)

 \(3:8=\dfrac{3}{8}\)

\(8:9=\dfrac{8}{9}\)

\(4:7=\dfrac{4}{7}\)

\(12:5=\dfrac{12}{5}\)

b)

 \(7=\dfrac{7}{1}\)

\(9=\dfrac{9}{1}\)

\(21=\dfrac{21}{1}\)

\(40=\dfrac{40}{1}\)

a) $6:7 = \frac{6}{7}$   ;   $7:9 = \frac{7}{9}$                                                

$5:4 = \frac{5}{4}$   ;     $11:4 = \frac{{11}}{4}$

b) $9:3 = \frac{9}{3} = 3$        

$12:6 = \frac{{12}}{6} = 2$                         

$24:8 = \frac{{24}}{8} = 3$

ngu ke tao tao con gioi hon may day

bạn Hương ơi lễ phép xíu trên mạng nhe, mình nhắc vậy chứ ko muôn  nói xấu bạn, thông cảm hộ mình!

cảm ơn

\(14:7=\dfrac{14}{7}\)

\(3:10=\dfrac{3}{10}\)

\(9:8=\dfrac{9}{8}\)

\(6:6=\dfrac{6}{6}\)
