d)5/8 e 7/9

Answer 1

razão

a)
$5~~e~~7= \frac{5}{7}$

b)
$25~~e~~11= \frac{25}{11}$

c)
$\frac{1}{3} ~~e~~ \frac{1}{2} = \frac{1}{3} \div \frac{1}{2} = \frac{1}{3} . \frac{2}{1} = \frac{2}{3}$

d)
$\frac{5}{8} ~~e~~ \frac{7}{9} = \frac{5}{8} \div \frac{7}{9} = \frac{5}{8} . \frac{9}{7}= \frac{45}{56}$
