a)
[tex]\frac{1}{4}= \frac{3}{12} [/tex] > [tex]\frac{1}{6} = \frac{2}{12} [/tex]
b)
[tex]\frac{3}{10} =\frac{9}{30} [/tex] > [tex]\frac{1}{15} = \frac{2}{30} [/tex]
c)
[tex]\frac{3}{27} = \frac{6}{54} [/tex] < [tex]\frac{7}{18} = \frac{21}{54} [/tex]
d)
[tex]\frac{7}{8} = \frac{35}{40} [/tex] > [tex]\frac{7}{20} = \frac{14}{40} [/tex]
