Answer 1

Respuesta:

$\frac{2}{3} \times \frac{3}{4} = \frac{2(4)}{3(4)} \times \frac{3(3)}{4(3)} = \frac{8}{12} \times \frac{6}{12} = \frac{48 }{12} = 4$

$\frac{5}{2} \times \frac{8}{15} = \frac{5(15)}{2(15)} \times \frac{8(2)}{15(2)} = \frac{75}{30} \times \frac{16}{30} = \frac{1200}{30} = 40$

$\frac{4}{9} \times \frac{12}{16} = \frac{4(16)}{9(16)} \times \frac{12(9)}{16(9)} = \frac{64}{144} \times \frac{108}{144} = \frac{6912}{144} = 48$

$\frac{3}{4} \times \frac{7}{9} = \frac{3(9)}{4(9)} \times \frac{7(4)}{9(4)} = \frac{27}{36} \times \frac{28}{36} = \frac{756}{36} = 21$

$\frac{8}{9} \times \frac{7}{9} = \frac{56}{9} = 6 \frac{2}{9}$

$\frac{8}{9} \times \frac{15}{10} = \frac{8(10)}{9(10)} \times \frac{15(9)}{10(9)} = \frac{80}{90} \times \frac{135}{90} = \frac{10800}{90} = 120$
