$\frac{(4,5*1\frac{2}{3}-6,75)*\frac{2}{3}}{(3\frac{1}{3}*0,3+5\frac{1}{3}*\frac{1}{8}):2\frac{2}{3}}+\frac{1\frac{4}{11}*0,22:0,3-0,96}{(0,2-\frac{3}{40})*1,6}=\frac{0,5}{0,625}+\frac{0,04}{0,2}=0,8+0,2=1$

1) $(4,5*1\frac{2}{3}-6,75)*\frac{2}{3}=(4,5*\frac{5}{3}-6,75)*\frac{2}{3}=(\frac{4,5*5}{3}-6,75)*\frac{2}{3}=(7,5-6,75)*\frac{2}{3}=0,75*\frac{2}{3}=\frac{0,75*2}{3}=0,25*2=0,5$

2) $(3\frac{1}{3}*0,3+5\frac{1}{3}*\frac{1}{8}):2\frac{2}{3}=(\frac{10}{3}*0,3+\frac{16}{3}*\frac{1}{8}):\frac{8}{3}=(\frac{10*0,3}{3}+\frac{16}{3*8})*\frac{3}{8}=(1+\frac{2}{3})*\frac{3}{8}=\frac{3}{8}+\frac{2*3}{3*8}=\frac{3}{8}+\frac{2}{8}=\frac{5}{8}=0,625$

3) $1\frac{4}{11}*0,22:0,3-0,96=\frac{15}{11}*0,22:0,3-0,96=\frac{15*0,22}{11}:0,3-0,96=0,3:0,3-0,96=1-0,96=0,04$

4) $(0,2-\frac{3}{40})*1,6=(0,2-0,075)*1,6=0,125*1,6=0,2$
