1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78
5/6s + 3/4 = 11/12 10/12s + 9/12 = 11/12 10/12s = (11 - 9)/12 10/s = 2 s = 5
0 + 12 1 + 11 2 + 10 3 + 9 4 + 8 5 + 7 6 + 6 7 + 5 8 + 4 9 + 3 10 + 2 11 + 1 12 + 0 (I'm not going into negitives.)
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 210
10 1/3 + 7/9 = 11 1/9 or eleven and one ninth.
3/5 + 9/10 = 6/10 + 9/10 = 15/10 = 3/2 or 11/2
9/10 + 3/5 = 9/10 + 6/10 = 15/10 = 3/2 or 11/2
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78
11 plus 5-10 plus 20-9 plus 14-10 is equal to 21
12+8+10+12+11+9 = 62
9/10 + 6/10 = 15/10 (Which can be written as 3/2 or 11/2)
It is 11 over 15.
10+9+15+8+4+6+11=63
6 9/10 + 3 2/3 = 69/10 + 11/3 = (207 + 110)/30 = 317/30
2.3 plus 7.8 is 2 3/10 + 7 8/10 or 9 11/10 or 10 1/10 ot 10.1.
