Answer 1

Respuesta:

$a. \: \frac{4}{12} \times \frac{3}{4} = \frac{4 \times 3}{12 \times 4} = \frac{12}{48} = \frac{1}{4}$

$b. \: \frac{ - 3}{7} \times \frac{ - 14}{9} = \frac{ - 3 \times - 14}{7 \times 9} = \frac{42}{63} = \frac{2}{3}$

$c. \: \frac{1}{3} \times \frac{1}{2} = \frac{1 \times 1}{3 \times 2} = \frac{1}{6}$

$d. \: \frac{ - 6}{15} \times \frac{3}{2} = \frac{ - 6 \times 3}{15 \times 2} = \frac{ - 18}{30} = \frac{ - 3}{5}$

$e. \: \frac{8}{21} \times \frac{7}{4} = \frac{8 \times 7}{21 \times 4} = \frac{56}{84} = \frac{2}{3}$

$f. \: \frac{2}{5} \times 5 = \frac{2}{1} = 2$

$g. \: \frac{ - 15}{2} \times \frac{ - 4}{5} = \frac{ - 15 \times - 4}{2 \times 5} = \frac{60}{10} = \frac{6}{1} = 6$

$h. \: \frac{5}{6} \times \frac{ - 9}{4} = \frac{ - 45}{24} = \frac{ - 15}{8}$
