Answer 1

1) 3 + 1/7 = 21+1/7 = 22/7

2) 6+5$\frac{2}{9}$ = 6+5+$\frac{2}{9}$ = 11+$\frac{2}{9}$ =11$\frac{2}{9}$

3)  5+4$\frac{9}{10}$ = 5+4+$\frac{9}{10}$ = 9$\frac{9}{10}$

4) 9$\frac{13}{26}$ + 23 = 9+$\frac{13}{26}$+23 = 32$\frac{13}{26}$

5) 4$\frac{2}{6}$+ 2$\frac{3}{6}$ = (4+2)+(2/6 + 3/6) = 6$\frac{5}{6}$

6) 11$\frac{9}{13}$ + 8$\frac{3}{13}$ = (11+80)+(9/13 + 3/13) = 19$\frac{12}{13}$

7) 6$\frac{5}{16}$ + 2$\frac{3}{16}$ = (6+2)+(5/16 + 3/16) = 8$\frac{8}{16}$ = 8$\frac{1}{2}$

8) 2$\frac{5}{22}$ + 8$\frac{15}{22}$ = (2+8)+(5/22 + 15/22) = 10$\frac{20}{22}$ = 10$\frac{10}{11}$

9) 5$\frac{29}{40}$ +4 $\frac{31}{40}$ = (4+5)+(29/40 +31\40) = 10$\frac{1}{2}$

Answer 2

Пошаговое объяснение:

1) 3 + 1/7 = 3 1/7

2) 6 + 5 2/9 = 11 2/9

3) 5 + 4 9/10 = 9 9/10

4) 9 13/16 + 23 = 32 13/16

5) 4 2/6 + 2 3/6 = 6 5/6

6) 10 9/13 + 8 3/13 = 18 12/13

7) 6 5/16 + 2 3/16 = 8 8/16 = 8 1/2

8) 2 5/22 + 8 15/22 = 10 20/22 = 10 10/11

9) 5 29/40 + 4 31/40 = 9 60/40 = 9 3/2 = 10 1/2
