Question

Resolver las siguientes multiplicaciones,simplificando previamente cuando sea posible ​

Answer 1

Explicación paso a paso:

a)

[tex] \frac{3}{4} \times - \frac{5}{21} = - \frac{3 \times 5}{4 \times 21} = - \frac{15}{84} = - \frac{5}{28} [/tex]

b)

[tex] - \frac{24}{25} \times \frac{75}{18} = - \frac{24 \times 75}{25 \times 18} = - \frac{1800}{450} = - \frac{180}{45} = - \frac{36}{9} = - \frac{12}{ 3 } = - 4[/tex]

c)

[tex] - \frac{144}{35} \times - \frac{49}{48} = \frac{144 \times 49}{35 \times 48} = \frac{(48 \times 3) \times 49}{35 \times 48} = \frac{3 \times 49}{35} = \frac{147}{35} = \frac{21}{5} [/tex]
