Answer 1

Salut! Am atasat rezolvarea. Succes! :)

Answer 2

2.

$\frac{3}{8} :\frac{1}{2}$   (avem impartire, deci rasturnam ultima fractie)

$\frac{3}{8}* \frac{2}{1}$  (simplificam 2 cu 8)

$\frac{3}{4} *1\\\\=\frac{3}{4}$

3.

$2\frac{1}{5} :4\frac{1}{10}$   (introducem intregii)

$\frac{2*5+1}{5} :\frac{4*10+1}{10}$  (ii voi introduce treptat)

$\frac{10+1}{5} :\frac{40+1}{10} \\\\\frac{11}{5} :\frac{41}{10}$     (rasturnam din nou ultima fractie)

$\frac{11}{5}* \frac{10}{41}$    (simplificam 10 cu 5)

$\frac{11}{1} *\frac{2}{41} \\\\=\frac{22}{41}$
