a(
[tex]a) \: \: \frac{22}{36} \times \frac{1}{3} \times \frac{81}{11} = \frac{22}{108} \times \frac{81}{11} = \frac{1782}{1188} simplificat \: prin6 = \frac{297}{298} [/tex]
b)
[tex] \frac{50}{26} \times \frac{1}{10} \times \frac{2}{15} = \frac{50}{260} \times \frac{2}{15} = \frac{10}{390} = \frac{1}{39} [/tex]
