Răspuns:

Explicație pas cu pas:

4$\frac{9}{10}$*$\frac{35}{42}$=$\frac{4*10+9}{10}$*$\frac{35}{42}$=$\frac{49}{10}*\frac{35}{42}=\frac{7*7}{2*5} *\frac{5*7}{6*7}=\frac{7*7}{6*2}=\frac{49}{12}=4,08$

$2\frac{13}{16}* 2\frac{10}{27}=\frac{2*16+13}{16}*\frac{2*27+10}{27}=\frac{45}{16}*\frac{64}{27} =\frac{9*5*8*8}{8*2*9*3}=\frac{20}{3}=6,(6)$
