Question

calcula estás multiplicaciones de números naturales y fracciones
5×4/9 9×3/7. 5/9×6. 7/8×9
4/7×5×3/8. 6/7×2/9×5​

Answer 1

$5 \times \frac{4}{9} = \frac{20}{9}$

$9 \times \frac{3}{7} = \frac{27}{7}$

$\frac{5}{9} \times 6 = \frac{30}{9}$

lo simplificamos

$\frac{10}{3}$

$\frac{7}{8} \times 9 = \frac{63}{8}$

$\frac{4}{7} \times 5 \times \frac{3}{8} = \frac{60}{56}$

simplificamos

$\frac{60}{56} = \frac{15}{14}$

$\frac{6}{7} \times \frac{2}{9} \times 5 = \frac{60}{63} = \frac{20}{21}$
