Answer 1

Explicație pas cu pas:

Buna !!

$a) \frac{3}{2} \times \frac{15}{4} = \frac{3 \times 15}{2 \times 4} = \frac{45}{8}$

$b) \frac{4}{5} \times \frac{7}{12} = \frac{4 \times 7}{5 \times 12} = \frac{28}{60} ^{(2} = \frac{14}{30} ^{(2} = \frac{7}{15}$

$c) \frac{8}{7} \times \frac{4}{15} = \frac{8 \times 4}{7 \times 15} = \frac{32}{105}$

$d) \frac{4}{9} \times \frac{36}{5} = \frac{4 \times 36}{9 \times 5} = \frac{144}{45} ^{(9} = \frac{16}{5}$

Succes !!;)
