Answer:
1. 12 + 3/7
= 12/1 + 3/7
=84/ 7 + 3/7
=87/7 or 12 3/7
2.2/22 +2/7
= 14/ 154 + 44/154
=58/154
=29/77
2 2/2 +27
=6/2 + 2/7
=42/14 + 4+14
=46/14
=23/7 or 3 2/7
3. 2 2/3 +4 5/6
=8/3 + 29/6
=16/6 + 29/6
=45/6
=15/2 or 7 1/2
4.12-1/3
= 12/1- 1/3
=36/3- 1/3
=35/3 or 11 2/3
5.20-2/7
= 20/1 - 2/7
=140/7- 2/7
