a)
[tex] \frac{25}{75} = \frac{1}{3} [/tex]
b)
[tex] \frac{ \frac{7}{3} }{ \frac{7}{9} } = \frac{7}{3} \times \frac{9}{7} = 3[/tex]
c)
[tex] \frac{ \frac{4}{3} }{ \frac{51}{90} } = \frac{4}{3} \times \frac{90}{51} = \frac{120}{51} = \frac{40}{17} = 2 \frac{6}{17} [/tex]
d)
[tex] \frac{ \frac{5}{2} }{ \frac{1}{6} } = \frac{5}{2} \times 6 = 15[/tex]
