Answer 2

Respuesta:

$1.$

$a) \frac{7}{5} = \frac{14}{10} = \frac{21}{15} = \frac{28}{20} = \frac{35}{25}$

$b) \frac{4}{5} = \frac{8}{10} = \frac{12}{15} = \frac{16}{20} = \frac{20}{25} = \frac{24}{30}$

$c) \frac{30}{45} = \frac{6}{9} = \frac{2}{3} = \frac{10}{15} = \frac{12}{18} = \frac{18}{27}$

$d) - \frac{16}{20} = - \frac{4}{5} = - \frac{8}{10} = - \frac{32}{40} = - \frac{48}{60}$

$e) - \frac{9}{5} = - \frac{18}{10} = - \frac{27}{15} = - \frac{36}{20} = - \frac{45}{25}$

$d) - \frac{1}{4} = - \frac{2}{8} = - \frac{3}{12} = - \frac{4}{16} = - \frac{5}{20}$

$2.$

$a) \frac{30}{150} = \frac{30 \div 30}{150 \div 30} = \frac{1}{5}$

$b) \frac{28}{42} = \frac{28 \div 2}{42 \div 2} = \frac{14}{21}$

$c) \frac{18}{3} = \frac{18 \div 3}{3 \div 3} = 6$
