1 17/60
1/4 + 1/3 = 3/12 + 4/12 (12 is the least common multiple of 3 and 4) = 7/12
5/6
19/12 or 1 and 7/12
5/12 + 7/12 = 12/12 Essentially 12/12 is a whole, so it is equal to 1.
7/12 + 1/3 = 11/12
1/12 + 7/9 is 31/36
7 over 12
7/12 + 8/12 = 15/12 = 1 and 3/12 = 1 and 1/4
-7/12 + 10/12 = 3/12 = 1/4
1 17/60
0 7/12
The answer is 9 over 12 or 3 over 4
1/4 + 1/3 = 3/12 + 4/12 (12 is the least common multiple of 3 and 4) = 7/12
1/3 + 1/4 = 4/12 + 3/12 = 7/12
5/6
19/12 or 1 and 7/12
