Answer 1

$a) \: ( \frac{12}{25} \div \frac{4}{5} ) \div \frac{9}{35} \\ \frac{60}{100} \div \frac{9}{35} = \frac{2100}{900} = \frac{7}{3}$

$b) \: \frac{12}{25} \div ( \frac{4}{5} \div \frac{9}{35} ) \\ \frac{12}{25} \div \frac{140}{45} = \frac{540}{3500} = \frac{27}{175}$

$c) \: ( \frac{25}{36} \div \frac{7}{16}) \div ( \frac{60}{49} \div \frac{162}{7} ) \\ \frac{400}{252} \div \frac{420}{7938} = \frac{3175200}{105840} = 30$

$d) \: ( \frac{11}{12} \div \frac{13}{18} ) \div \frac{22}{33} \\ \frac{198}{156} \div \frac{22}{33} = \frac{6534}{3432} = \frac{99}{52}$

$e) \: ( \frac{19}{45} \div \frac{7}{30}) \div \frac{19}{21} \\ \frac{570}{315} \div \frac{19}{21} = \frac{11970}{5985} = 2$

$f) \: ( \frac{13}{12} \div \frac{7}{15} ) \div \frac{39}{70} \\ \frac{195}{84} \div \frac{39}{70} = \frac{13650}{3276} = \frac{25}{6}$

ți am zis și așa dar ți am dat și poză
