a)
[tex] \frac{3}{7} \times \frac{14}{27} = \frac{1}{1} \times \frac{2}{9} = \frac{2}{9} [/tex]
b)
[tex] \frac{3}{5} \times \frac{15}{24} = \frac{1}{1} \times \frac{3}{8} [/tex]
c)
[tex] \frac{7}{12} \times \frac{3}{7} = \frac{1}{4} \times \frac{1}{1} = \frac{1}{4} [/tex]
d)
[tex] \frac{5}{27} \times \frac{6}{35} = \frac{1}{9} \times \frac{2}{7} = \frac{2}{63} [/tex]
e)
[tex] \frac{3}{8} \times \frac{4}{9} = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6} [/tex]
f)
[tex] \frac{5}{16} \times \frac{4}{15} = \frac{1}{4} \times \frac{1}{3} = \frac{1}{12} [/tex]
g)
[tex] \frac{4}{9} \times \frac{3}{20} = \frac{1}{3} \times \frac{1}{5} = \frac{1}{15} [/tex]
h)
[tex] \frac{33}{70} \times \frac{10}{11} = \frac{3}{7} \times \frac{1}{1} = \frac{3}{7} [/tex]
