Answer 1

Răspuns:

7.

$\frac{7}{10} :\frac{3}{2} =\frac{7}{10} *\frac{2}{3} =\frac{7}{5*3} =\frac{7}{15}$

$\frac{9}{5} :\frac{7}{10} =\frac{9}{5}*\frac{10}{7} =\frac{9*2}{7} =\frac{18}{7} =4\frac{4}{7}$

$1\frac{1}{3} :10=\frac{4}{3} *\frac{1}{10} =\frac{2}{3*5} =\frac{2}{15}$

$2:4\frac{1}{5} =2:\frac{21}{5}=2*\frac{5}{21}=\frac{10}{21}$

$4\frac{1}{10} :2\frac{1}{2}= \frac{41}{10} :\frac{5}{2}=\frac{41}{10} *\frac{2}{5} =\frac{41}{5*5} =\frac{41}{25} =1\frac{16}{25}$

8.

18:3=6

$\frac{15}{4}:3=\frac{15}{4} *\frac{1}{3} =\frac{5}{4}$

$\frac{17}{3} :3=\frac{17}{3} *\frac{1}{3} =\frac{17}{9}$

$1\frac{1}{2} :3=\frac{3}{2} *\frac{1}{3} =\frac{1}{2}$
