Penjelasan dengan langkah-langkah:
1. ) 3 1/2 + 1 1/4 + 2 3/8 =
= (3+1+2) + 1/2 + 1/4 +3/8
= 6 + (4+2+3)/8
= 6 + 9/8
=6 + 1 + (1/8)
= 7 1/8

2.) 5 2/3 + 3 1/6 + 4 3/4 =
= (5+3+4) + 2/3 + 1/6 + 3/4
= 12 + (8+2+9)/12
= 12 + 19/12
= 12 + 1 + (7/12)
= 13 7/12

3. ) 2 3/5 + 5 1/4 + 3 1/2 =
= (2+5+3) + (3/5 + 1/4 + 1/2)
= 10 + (12+5+10)/20
= 10 + 27/20
= 10 + 1 7/20
= 11 7/20
____________________________
8. ) 4 14/15 + 9 4/5 + 8 9/10 =
= (4+9+8) + (14/15 + 4/5 + 9/10)
= 21 + (28+24+27)/30
= 21 + 79/30
= 21 + 2 19/30
= 23 19/30
____________________________
9.) 11 3/8 + 7 17/20 + 9 3/5 =
= (11+7+9) + (3/8 + 17/20 +3/5)
= 27 + (15+34+24)/40
= 27 + 73/40
= 27 + 1 33/40
= 28 33/40
