B) 39 e 26
C)3/8 e 6/5
D)2/3 e 13/14

Answer 1

a)

$\frac{30}{50} = \frac{3}{5}$
b)
$\frac{39}{26} = \frac{3 \times 13}{2 \times 13} = \frac{3}{2}$
c)
$\frac{ \frac{3}{8} }{ \frac{6}{5} } = \frac{3}{8} \times \frac{5}{6} = \frac{15}{48} = \frac{5}{16}$
d)
$\frac{ \frac{2}{3} }{ \frac{13}{14} } = \frac{2}{3} \times \frac{14}{13} = \frac{28}{39}$
