Question

- 5/11 - (- 5/11) = ? -8 - (-1/7) = ? -5/12 - (-4) = ?

Answer 1

1) 0, так как минус на минус дает плюс и числа складываются
2) -7 целых 6/7 
3) 3 целых 7/12

Answer 2

1. 5/11 - (-5/11) = 5/11 + 5/11 = 10/11

2. -8 - (-1/7) = -8 + 1/7 = -57/7 (you can also write it as a mixed number: -8 1/7)

3. -5/12 - (-4) = -5/12 + 48/12 = 43/12 (you can also write it as a mixed number: 3 7/12)
