Answer 1

$\displaystyle\bf\\1)\\\\2\frac{1}{2} +4\frac{5}{6} =\Big(2+4\Big)+\Big(\frac{1}{2} +\frac{5}{6} \Big)=6+\frac{3+5}{6} =6+\frac{8}{6} =6+1\frac{1}{3} =7\frac{1}{3} \\\\\\2)\\\\7\frac{1}{3} :3\frac{2}{3} =\frac{22}{3} :\frac{11}{3} =\frac{22}{3} \cdot\frac{3}{11} =2\\\\\\3)\\\\\frac{3}{4} :\frac{3}{5} =\frac{3}{4} \cdot\frac{5}{3} =\frac{5}{4}=1,25\\\\\\4)\\\\2-1,25=0,75$
