1. 2 2/3 + 1 5/8

= 8/3 + 13/8

= 8×8+3×13/24

= 103/24

= 4 7/24

2. 2 1/6 + 3 1/9 + 5 7/36

= 2 1/6 + 3 1/9

= 13/6 + 28/9

= 3×13+2×28/18

= 95/18

= 5 5/18

5 5/18 + 5 7/36

= 95/18 + 187/36

= 2×95+187/36

= 377/36

= 10 17/36

3. 3 1/3 + 4 1/4 + 5 1/5

= 3 1/3 + 4 1/4

= 10/3 + 17/4

= 4×10+3×17/12

=91/12

= 7 7/12

7 7/12 + 5 1/5

= 91/12 + 26/5

= 5×91+12×26/60

= 767/60

= 12 47/60

4. 6 7/12 + 7 6/7 + 8 11/21

= 6 7/12 + 7 6/7

= 79/12 + 55/7

= 7×79+12×55/84

= 1213/84

= 14 37/84

14 37/84 + 8 11/21

= 1213/84 + 179/21

= 1213+4×179/84

= 1929/84

= 643/28

= 22 27/28

5. 4 5/6 + 8 4/15 + 1 5/9

= 4 5/6 + 8 4/15

= 29/6 + 124/15

= 5×29+2×124/30

= 393/30

= 131/10

= 13 1/10

13 1/10 + 1 5/9

= 131/10 + 14/9

= 9×131+10×14/90

= 1319/90

= 14 59/90
