Answer 1

Răspuns:

1. a)

$\frac{3}{6} \div \frac{6}{7} = \frac{3}{6} \times \frac{6}{7} = \frac{3}{7}$

b)

$\frac{1}{6} \div \frac{1}{712} = \frac{1}{6} \times \frac{712}{1} = 117.(6)$

c)

$\frac{1}{3} \div \frac{2}{9} = \frac{1}{3} \times \frac{9}{2} = \frac{3}{2}$

d)

$\frac{1}{9} \div \frac{1}{7} = \frac{1}{9} \times \frac{7}{1} = \frac{7}{9}$

e)

$\frac{7}{1} \div \frac{7}{3} = \frac{7}{1} \times \frac{3}{7} = 3$

f)

$\frac{5}{8} \div \frac{2}{3} = \frac{5}{8} \times \frac{3}{2} = \frac{15}{16}$

g)

$\frac{7}{9} \div \frac{1}{3} = \frac{7}{9} \times \frac{3}{1} = \frac{7}{3}$

h)

$\frac{5}{8} \div \frac{1}{2} = \frac{5}{8} \times \frac{2}{1} = \frac{5}{4}$

succes!
