2 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 106
1.4.
12 and 10/8 = 13 and 2/8 = 131/4
7/12 + 8/12 = 15/12 = 1 and 3/12 = 1 and 1/4
1/12 + 4/6 = 1/12 + 8/12 = 9/12 = 3/4.3 over 4 is 1 over 12 plus 4 over 6.
12+8+10+12+11+9 = 62
3/8 + 5/12 = 9/24 + 10/24 = 19/24
10 plus 8 over 2 = 14
12+14=26+10=36+24=60+10=70+8=78 the answer is 78
6/12 = 1/2 = 5/10 so 6/12 + 3/10 = 5/10 + 3/10 = 8/10 = 4/5
25/40 + 12/40 = 37/40
5/8 + 5/12 = 15/24 + 10/24 = 25/24 or 11/24
8/12 + 3/12 = 11/12
5/12 plus 1/8 = 13/24
12/10+2=12
5 over 8 as a fraction plus 7 over 12 = 15/24
(7 over 12) + (5 over 8) = 1.20833333
