a) 1\2 e 3
b) 3 e 1\3
c) 1\3 e 1\2
d) 5\8 e 7\9​

Answer 1

Explicação passo-a-passo:

$a) \frac{1}{2} \div 3 = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6}$

$b)3 \div \frac{1}{3} = 3 \times 3 = 9$

$c) \frac{1}{3} \div \frac{1}{2} = \frac{1}{3} \times 2 = \frac{2}{3}$

$d) \frac{5}{8} \div \frac{7}{9} = \frac{5}{8} \times \frac{9}{7} = \frac{45}{56}$

Answer 2

Explicação passo-a-passo:

A)

$\dfrac{1}{2} \div 3 = \dfrac{1}{2} \times \dfrac{1}{3} = > \dfrac{1}{6}$

B)

$3 \div \dfrac{1}{3} = 3 \times \dfrac{3}{1} = \dfrac{9}{1} = > 9$

C)

$\dfrac{1}{3} \div \dfrac{1}{2} = \dfrac{1}{3} \times \dfrac{2}{1} = > \dfrac{2}{3}$

D)

$\dfrac{5}{8} \div \dfrac{7}{9} = \dfrac{5}{8} \times \dfrac{9}{7} = \dfrac{45}{56}$
