alguien me prodria explicar como es,es urgenteee​

Answer 1

Respuesta:

Multiplicación de fracciones:

Se multiplican numerador con numerador y denominador con denominador:

$\frac{-3}{4} * -\frac{-3}{6} = \frac{-3*(-3)}{4*6} = \frac{9}{24}\\\\\frac{3}{4} *\frac{-3}{6} = \frac{3*(-3)}{4*6} = \frac{-9}{24}\\\\ \frac{2}{9} * \frac{-3}{7} = \frac{2(-3)}{9*7} = \frac{-6}{63} = \frac{-2}{21}\\\\ \frac{4}{3} *\frac{-9}{10} = \frac{4*(-9)}{3*10} = \frac{-36}{30} = \frac{-6}{5}\\\\ \frac{6}{8} * \frac{7}{9} = \frac{6*7}{8*9} = \frac{42}{72} = \frac{7}{12}$

División de fracciones:

Se aplica la ley de extremos y medios, así:

$\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a*d}{b*c}$

$\frac{\frac{-3}{4}}{\frac{-1}{3}} = \frac{-3*3}{4*(-1)} = \frac{9}{4}\\\\ \frac{\frac{9}{12}}{\frac{-3}{6}} = \frac{9*6}{12*(-3)} = \frac{54}{-36} = \frac{3}{-2}\\\\ \frac{ \frac{8}{9}}{\frac{-3}{8}} = \frac{8*8}{9*(-3)} = \frac{64}{-27}$
