Answer 2

[(2,2 - 4/5)×13/7+(5,2-22/5)]:22/3 + 1/3 =

= [(22/10-4/5)×13/7+(52/10-22/5)]:22/3 + 1/3 =

= [(22-4×2)/10×13/7 +(52-2×22)/10]:22/3+1/3 =

= [(22-8)/10×13/7+(52-44)/10]:22/3+1/3 =

= [14/10×13/7+8/10] : 22/3+1/3 =

= (26/10+8/10) : 22/3 + 1/3 =

= 34/10 ×3/22+ 1/3 =

= 102/220 + 1/3 =

= (102×3+220)/660=

= (306+220)/660 =

= 526/660 =

= 263/330
