Answer 1

Explicación paso a paso:

$a) \: \frac{4}{21} \\ b) \: \frac{6}{15} = \frac{2}{5} \\ c) \: \frac{130}{25} = \frac{26}{5} \\ d) \: \frac{30}{36} = \frac{15}{18} = \frac{5}{6} \\ e) \: \frac{15}{15} \div \frac{2}{3} = \frac{45}{30} = \frac{15}{10} = \frac{3}{2} \\ f) \: (\frac{12}{48}) \div ( \frac{6}{12} ) = \frac{144}{288} = \frac{72}{144} = \frac{36}{72} = \frac{18}{36 =} = \frac{9}{18} = \frac{3}{6} = \frac{1}{2}$
