Răspuns:

a)

$3 \div \frac{5}{2} = \frac{1}{3} \div \frac{5}{2} = \frac{1}{3} \times \frac{2}{5} = \frac{2}{15}$

b)

$5 \div \frac{3}{4} = \frac{1}{5} \div \frac{3}{4} = \frac{1}{5} \times \frac{4}{3} = \frac{4}{15}$

c)

$2 \div 3 \frac{1}{2} = \frac{1}{2} \div \frac{7}{2} = \frac{1}{2} \times \frac{ {2}^{2} }{7} = \frac{1}{1} \times \frac{1}{7} = \frac{1}{7}$

d)

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