1a.  \(\dfrac{19}{41};\dfrac{201}{307};\dfrac{113}{71};\dfrac{14}{9};\dfrac{36}{1}\)

1b. \(\dfrac{12}{1};\dfrac{79}{1};\dfrac{219}{1};\dfrac{2010}{1};\dfrac{0}{1};\dfrac{1}{1};\dfrac{7981}{1}\)

\(6=\dfrac{12}{2}\)

\(9=\dfrac{18}{2}\)

\(4=\dfrac{8}{2}\)

\(12=\dfrac{24}{2}\)

\(11=\dfrac{22}{2}\)

\(10=\dfrac{20}{2}\)

\(13=\dfrac{26}{2}\)

\(23=\dfrac{46}{2}\)

\(30=\dfrac{60}{2}\)

6   =   6 1 ;   1   =   1 1 27   =   27 1 ;   0   =   0 1 3   =   3 1

6=6/1                         

1=1/1

27=27/1

0=0/1

3=3/1

9b=63b/7

1.
a) 10=\(\dfrac{40}{4}\)

b) 25= \(\dfrac{100}{4}\)

2.

a) 11=\(\dfrac{11}{1}\)

b) 276=\(\dfrac{276}{1}\)

c) 158=\(\dfrac{158}{1}\)

3.

\(\dfrac{1}{1};\dfrac{2}{2};\dfrac{3}{3};\dfrac{4}{4};\dfrac{5}{5}\)

$5 = \frac{5}{1}$  ;   $14 = \frac{{14}}{1}$   ;   $327 = \frac{{327}}{1}$

$1 = \frac{1}{1}$  ;   $0 = \frac{0}{1}$

\(5=\dfrac{5}{1}\)

\(14=\dfrac{14}{1}\)

\(327=\dfrac{327}{1}\)

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

\(0=\dfrac{0}{1}\)

\(10=\dfrac{120}{12}\)

\(5=\dfrac{120}{24}\)

\(20=\dfrac{120}{6}\)

\(4=\dfrac{120}{30}\)

\(12=\dfrac{120}{10}\)

\(30=\dfrac{120}{40}\)

\(10=\dfrac{10\cdot6}{6\cdot1}=\dfrac{60}{6}\)

\(6=\dfrac{6\cdot6}{1\cdot6}=\dfrac{36}{6}\)

\(101=\dfrac{101\cdot6}{6}=\dfrac{606}{6}\)

\(9=\dfrac{9\cdot6}{6}=\dfrac{54}{6}\)

\(22=\dfrac{22\cdot6}{6}=\dfrac{132}{6}\)

giúp mik với ạ!!!

\(10=\dfrac{60}{6}\)

\(6=\dfrac{36}{6}\)

\(101=\dfrac{606}{6}\)

\(9=\dfrac{54}{6}\)

\(22=\dfrac{132}{6}\)
