$\dfrac{2 {}^{ \div 2} }{10 {}^{ \div 2} }$

1/5

B)

$\dfrac{4}{7} \times \dfrac{3}{2}$

$\dfrac{12}{14}$

$\dfrac{12 {}^{ \div 2} }{14 {}^{ \div 2} }$

6/7

C)

$\dfrac{6}{5} \times \dfrac{5}{4}$

$\dfrac{30}{20}$

$\dfrac{30 {}^{ \div 10} }{20 {}^{ \div 10} }$

3/2

D)

$\dfrac{4}{18} \times \dfrac{9}{6}$

$\dfrac{36 {}^{ \div 36} }{108 {}^{ \div 36} }$

1/3

E)

$\dfrac{7}{6} \times \dfrac{32}{21}$

$\dfrac{224}{126}$

$\dfrac{224 {}^{ \div 14} }{126 {}^{ \div 14} }$

16/9

F)

$\dfrac{8}{9} \times \dfrac{2}{3} \times \times \dfrac{7}{6}$

$\dfrac{112}{162}$

$\dfrac{112 {}^{ \div 2} }{162 {}^{ \div 2} }$

56/81

G)

$\dfrac{10}{12} \times \dfrac{4}{5} \times \dfrac{25}{16}$

$\dfrac{1000}{960}$

$\dfrac{1000 {}^{ \div 40} }{960 {}^{ \div 40} }$

25/24

H)

$\dfrac{2}{7} \times \dfrac{21}{14} \times \dfrac{8}{6}$

$\dfrac{336}{588}$
