Bună!☕

$3 \times \frac{1}{2} = \frac{3}{1} \times \frac{1}{2} = \frac{3 \times 1}{1 \times 2} = \frac{3}{2}$

$5 \times \frac{3}{8} = \frac{5}{1} \times \frac{3}{8} = \frac{5 \times 3}{1 \times 8} = \frac{15}{8}$

$\frac{23}{18} \times 27 = \frac{23}{2} \times 3 = \frac{69}{2}$

$\frac{31}{45} \times 30 = \frac{31}{3} \times 2 = \frac{62}{3}$

$6 \times 3 \frac{1}{9} = 6 \times \frac{28}{9} = \frac{56}{ 3}$

$9 \times 5 \frac{7}{18} = 9 \times \frac{97}{18} = \frac{97}{2}$

$\frac{3}{8} \times \frac{9}{11} = \frac{27}{88}$

$\frac{16}{21} \times \frac{25}{27} = \frac{400}{567}$

$\frac{7}{8} \times 1 \frac{1}{7} = \frac{7}{8} \times \frac{8}{7} = 1$

$\frac{33}{100} \times 3 \frac{1}{3} = \frac{33}{100} \times \frac{10}{3} = \frac{11}{10}$

$3 \frac{1}{7} \times \frac{14}{33} = \frac{22}{7} \times \frac{14}{33} = \frac{4}{3}$

$\frac{7}{13} \times \frac{29}{56} = \frac{1}{13} \times \frac{29}{8} = \frac{29}{104}$

$\frac{25}{36} \times \frac{27}{50} = \frac{1}{4} \times \frac{3}{2} = \frac{3}{8}$
