Bună,:)

$a)3 \div \frac{5}{2} = 3 \times \frac{2}{5} = \frac{6}{5} = 1.2$

$b)5 \div \frac{3}{4} = 5 \times \frac{3}{4} = \frac{15}{4} = 3.75$

$c)8 \div \frac{1}{2} = 8 \div \frac{2}{1} = 4$

$d)2 \div 3\frac{1}{2} = 2 \div \frac{3}{2} = 2 \times \frac{2}{3} = \frac{4}{3} = 1.(3)$

$e) \frac{5}{3} \div 4 = \frac{3}{5} \times 4 = \frac{12}{5} = 1.4$

$f) \frac{8}{7} \div 6 = \frac{7}{8} \times 6 \: (simplifcam \: cu \: 3) = \frac{21}{4}$

$g) \frac{1}{3} \div 3 = \frac{3}{1} \times 3 = 1$

$h) 2\frac{2}{3} \div 2 = 3 \div 2 = 1.5$
