Answer 2

Let's solve each subtraction problem step by step:

1. 2 1/3 - 2/3: To subtract fractions, we need a common denominator. The common denominator here is 3. 2 1/3 = (6 + 1)/3 = 7/3 So, the calculation becomes: (7/3) - (2/3) = (7 - 2)/3 = 5/3

2. 4 5/9 - 8/9: The whole number part doesn't affect the fractional part in this subtraction, so we can directly subtract the fractions. 4 5/9 = (36 + 5)/9 = 41/9 So, the calculation becomes: (41/9) - (8/9) = (41 - 8)/9 = 33/9 = 3 2/9

3. 3 1/12 - 1 5/12: Again, the whole number part doesn't affect the fractional part in this subtraction. 3 1/12 = (36 + 1)/12 = 37/12 1 5/12 = (12 + 5)/12 = 17/12 So, the calculation becomes: (37/12) - (17/12) = (37 - 17)/12 = 20/12 = 1 8/12 = 1 2/3

4. 6 3/7 - 5 5/7: Once more, we can directly subtract the fractional parts since the whole number part doesn't interfere. 6 3/7 = (42 + 3)/7 = 45/7 5 5/7 = (35 + 5)/7 = 40/7 So, the calculation becomes: (45/7) - (40/7) = (45 - 40)/7 = 5/7

5. 2 3/8 - 1 7/8: Similarly, the whole number part doesn't impact the fractional part in this subtraction. 2 3/8 = (16 + 3)/8 = 19/8 1 7/8 = (8 + 7)/8 = 15/8 So, the calculation becomes: (19/8) - (15/8) = (19 - 15)/8 = 4/8 = 1/2

So, the results are:

1. 2 1/3 - 2/3 = 5/3
2. 4 5/9 - 8/9 = 3 2/9
3. 3 1/12 - 1 5/12 = 1 2/3
4. 6 3/7 - 5 5/7 = 5/7
5. 2 3/8 - 1 7/8 = 1/2
