Пошаговое объяснение:

1. $2-\frac{8}{5}=\frac{2}{1}-\frac{8}{5}=\frac{10-8}{5}=-\frac{2}{5}$

2. $4-\frac{9}{11}-\frac{27}{11}=\frac{44-9-27}{11}=\frac{8}{11}$

3. $2-\frac{16}{17} -\frac{18}{17}=\frac{34-16-18}{17}=0$

4. $3-\frac{21}{19}-\frac{16}{19}=\frac{57-21-16}{19}=\frac{20}{19} =1\frac{1}{19}$

5. $2-(\frac{26}{27}+\frac{24}{27})=2-\frac{50}{27}=\frac{54-50}{27} =\frac{4}{27}$

6. $2-(\frac{24}{25}-\frac{1}{25})=\frac{50}{25}-\frac{24}{25}+\frac{1}{25}=\frac{50-24+1}{25} =\frac{27}{25}=1\frac{2}{25}$
