Step-by-step Solution
Para multiplicar fracciones, multiplicamos los numeradores entre sí y los denominadores entre sí. Vamos a resolver los dos ejemplos que has dado.
a. \( -\frac{3}{4} * \frac{1}{2} \)
Multiplicamos los numeradores:
\[
-3 * 1 = -3
\]
Multiplicamos los denominadores:
\[
4 * 2 = 8
\]
Por lo tanto, el resultado es:
\[
-\frac{3}{8}
\]
b. \( \frac{3}{5} * \left(-\frac{6}{4}\right) \)
Multiplicamos los numeradores:
\[
3 * (-6) = -18
\]
Multiplicamos los denominadores:
\[
5 * 4 = 20
\]
Por lo tanto, el resultado es:
\[
-\frac{18}{20}
\]
Ahora simplificamos la fracción:
\[
-\frac{18}{20} = -\frac{9}{10} \quad (\text{dividiendo el numerador y el denominador entre 2})
\]
Así que los resultados finales son:
a. \( -\frac{3}{8} \)
b. \( -\frac{9}{10} \)
Quick Answer
a. \( -\frac{3}{8} \)
b. \( -\frac{9}{10} \)
