Answer 2

Răspuns:

a)

$\frac{12}{20} \times \frac{4}{6} \times \frac{5}{22} = \frac{2}{5} \times \frac{5}{22} = \frac{1}{11}$

b)

$\frac{22}{36} \times \frac{1}{3} \times \frac{81}{11} = \frac{2}{36} \times 27 = \frac{1}{18} \times 27 = \frac{1}{2} \times 3 = \frac{3}{2}$

c)

$\frac{50}{26} \times \frac{1}{10} \times \frac{2}{15} = \frac{5}{13} \times \frac{1}{15} = \frac{1}{13} \times \frac{1}{3} = \frac{1}{39}$

d)

$3 \frac{1}{4} \times 1 \frac{1}{3} \times \frac{1}{13} = \frac{13}{4} \times \frac{4}{3} \times \frac{1}{13} = \frac{1}{3}$
