13) 27/28 + 4 9/28 = 4 36/28 = 5 8/28 = 5 2/7
14) 4 7/20 + 2 17/20= 6 24/20 = 7 4/20 = 7 1/5
15) 23/26 + 11/26 = 34/26 = 1 8/26 = 1 4/13
16) 3 10/13 + 5 11/13 = 8 21/13 = 9 8/13
17) 8/11 + 5/11 = 13/11 = 1 2/11
18) 7 3/10 + 3 7/10 = 10 10/10 = 11
19) 7 8/19 + 1 13/19 = 8 21/19 = 9 2/19
20) 9/14 + 5 11/14 = 5 20/14 = 6 6/14 = 6 3/7
21) 7 1/8 + 3/8 = 7 4/8 = 7 1/2
22) 31 1/9 + 12 8/9 = 33 9/9 = 34
23) 9 7/12 + 1/12 = 9 8/12 = 9 2/3
24) 17 9/10+ 50 7/10 = 67 16/10 = 68 6/10 = 68 3/5

27/28+4 9/28=4 36/28=4 9/7=4+1 2/7=
=5 2/7
14
4 7/20+2 17/20=(4+2)+(7/20+17/20)=
=6+24/20=6+6/5=6+1 1/5=7 1/5=7,2
15
23/26+11/26=(23+11)/26=34/26=17/13=
=1 4/13
16
3 10/13+5 11/13=(3+5)+(10/13+11/13)=
=8+21/13=8+1 8/13=9 8/13
17
8/11+5/11=(8+5)/11=13/11=1 2/11
18
7 3/10+3 7/10=(7+3)+(3/10+7/10)=
=10+10/10=10+1=11
19
7 8/19+1 13/19=(7+1)+(8/19+13/19)=
=8+21/19=8+1 2/19=9 2/19
20
9/14+5 11/14=5+(9/14+11/14)=5+20/14=
=5+10/7=5+1 3/7=6 3/7
21
7 1/8+3/8=7+(1/8+3/8)=7+4/8=7+1/2=
=7 1/2=7,5
22
31 1/9+12 8/9=(31+12)+(1/9+8/9)=
=43+9/9=43+1=44
23
9 7/12+1/12=9+(7/12+1/12)=9+8/12=
=9+2/3=9 2/3
24
17 9/10+50 7/10=(17+50)+(9/10+7/10)=
67+16/10=67+8/5=67+1 3/5=68 3/5=68,6
