Пошаговое объяснение:
10 9/13 + 8 3/13 =(10+8)+(9/13+3/13)=18+(9+3)/13=18+12/13=18 12/13
6 5/16 + 2 3/6 =(6+2)+(5/16+3/6)=8+13/16=8 13/15
2 5/22 + 8 15/22 =(2+8)+(5/22+15/22)=10 + 20/22=10+10/11=10 10/11
5 29/ 40 + 4 31/40 =(5+4)+(29/40+31/40)=9 + (29+31)/40=9 + 60/40 = 9 + 3/2=9 + 1 1/2=9+1+1/2=10+1/2=10 1/2
