Answer 2

Răspuns:

$1) \: \frac{12}{16} \div \frac{8}{9} = \frac{6}{8} \times \frac{9}{8} = \frac{54}{64} = \frac{27}{32}$

$2) \frac{2}{7} \div \frac{10}{8} = \frac{2}{7} \times \frac{4}{5} = \frac{8}{35}$

$3) \: 2 \frac{1}{4} \div \frac{3}{5} = \frac{2 \times 4 + 1}{4} \times \frac{5}{3} = \frac{9}{4} \times \frac{5}{3} = \frac{15}{4}$

Sper că te-am ajutat! ^^
