Answer 1

1)...=6 1/4 - 3 1/2 - 2 1/7=
=6 7/28 - 3 14/28 - 2 4/28=
=5 35/28 - 3 14/28 - 1 4/28=
=1 17/18

2)...=4 1/6 - 4/6 - 1 3/6=
= 3 7/6 -4/6 - 1 3/6=
= 2

3)...= 3 1/2 + 3 3/4 + 2 3/10=
= 3 10/20 + 3 15/20 + 2 6/20=
= 8 31/20=
= 9 11/20

4)...=1/2 + 8/10=5/10+8/10=13/10=1 3/10

5)...=2 7/20 - 1 10/20=1 27/20-1 10/20=
=17/20

6)...=1 1/2 + 5/8=1 4/8 + 5/8=1 9/8=2 1/8

7)...=2 1/4 + 3/16 =2 4/16 + 3/16=2 7/16

Answer 2

6 1/4 - 3 1/2 - 1 7/8= 6 2/8 - 3 4/8 - 1 7/8 = 5 10/8 - 3 4/8 - 1 7/8 = 2 6/8 - 1 7/8 = 2 6/8 - 1 7/8 = 1 14/7 - 1 7/8 = 7/8
4 1/6 - 2/3 - 1 1/2 = 4 1/6 - 2/6 - 1 3/6 = 3 7/8 - 2/6 - 1 3/6 = 3 5/6 - 1 3/6 = 2 2/6 = 2 1/3
1 2/6 + 3 3/4 + 2 3/10 = 1 8/20 + 3 15/20 + 2 6/20 = 4 23/20 + 2 2/6 = 5 3/20 + 2 6/20 = 7 9/20
1/2 + 0,8 = 5/10 + 8/10 = 13/10 = 1 3/10
2 7/20 - 1 1/2 = 2 7/20 - 1 10/20 = 1 27/20 - 1 10/20 = 17/20
1,5 + 5/8 = 1,500 + 0,625 = 2,150 = 2,15
2,25 + 3/16 = 2 1/4 + 3/16 = 2 4/16 - 3/16 = 2 1/16 
Zrobiłam to najlepiej jak umiałam. Każdy z przykładów jest dokładnie rozpisany ;)
