[tex] \frac{46}{60} x \frac{13}{8 } = \frac{46x13}{60x8} = \frac{559}{480} [/tex]
[tex] \frac{15}{23} x \frac{9}{17} = \frac{15x9}{23x17} = \frac{135}{391} [/tex]
[tex] \frac{10}{12} x \frac{8}{14} = \frac{10x8}{12x14} = \frac{80}{168} [/tex]
[tex] \frac{17}{32} x \frac{24}{7} = \frac{17x24}{32x7} = \frac{408}{224} [/tex]
Espero que te ayude :)
