Answer 1

Respuesta:

45.

a)

$\frac{5}{7} \times \frac{14}{45} = \frac{2}{9}$

b)

$\frac{9}{11} \times \frac{33}{15} = \frac{3 \times 3}{1 \times 5} = \frac{9}{5}$

c)

$\frac{13}{72} \times \frac{63}{26} = \frac{1 \times 7}{8 \times 2} = \frac{7}{16}$

46.

a)

$\frac{4}{7} \times \frac{14}{3} \times \frac{9}{8} = \frac{1 \times 2 \times 3}{1 \times 1 \times 2} = \frac{3}{2}$

b)

$3 \times \frac{4}{5} \times \frac{10}{9} = \frac{1 \times 4 \times 2}{5 \times 3} = \frac{8}{15}$

c)

$1.2 \times \frac{8}{25} \times \frac{15}{6} \\ = \frac{12}{10} \times \frac{8}{25} \times \frac{15}{6} = \frac{8 \times 3} {2 \times 25} = \frac{24}{50}$

d)

$0.3 \times \frac{5}{7} \times \frac{21}{25} \\ \frac{3}{10} \times \frac{5}{7} \times \frac{21}{25} = \frac{ {3 \times 1 \times 3} }{2 \times 1 \times 25} = \frac{9}{50}$
