Answer 1

Exercitiul 4.

$a)\frac{5}{2} *\frac{1}{7} *\frac{1}{3}=\frac{5}{42}$

$b)\frac{2}{5} *\frac{2}{7} =\frac{4}{35}$

$c)\frac{3}{5} *\frac{2}{10} =\frac{3}{5} *\frac{1}{5} =\frac{3}{25}$

$d)\frac{5}{2}*\frac{3}{5} *\frac{1}{2}=\frac{1}{2} *3*\frac{1}{2}=\frac{3}{4}$

$e)4*\frac{3}{7} *\frac{7}{3}=4$

$f)5*\frac{13}{4}*\frac{5}{8}=\frac{325}{32}$

$g)\frac{7}{3} *\frac{7}{2} *4=\frac{7}{3} *7*2=\frac{98}{3}$

$h)\frac{1}{5} *\frac{5}{2} *3=\frac{1}{2}*3=\frac{3}{2}$

Exercitiul 5.

$a)\frac{15}{8} *\frac{19}{4}=\frac{285}{32}=8\frac{29}{32}=8,90$

$b)\frac{33}{5} *\frac{13}{4}=\frac{429}{20}=21\frac{9}{20}=21,45$

$c)\frac{17}{8} *\frac{21}{4}=\frac{357}{32}=11\frac{5}{32}=11.15$

$d)\frac{17}{5} *\frac{7}{2}=\frac{119}{10}=11\frac{9}{10}=11,9$
