Question

1)1 5/11-2 3/22 2)-1+3/5 3)-4 1/2*(-1 1/3) 4)-5 1/3+4/5

Answer 1

1)-15\22
2)-2\5
3)6
4)-4 8\15

Answer 2

1) 1 + 5/11 - 2 + 3/22 + 2 = 1 - 2 + 5/11 + 3/22 + 2 = -1 + 5/11 + 3/22 + 2 = -1 + 10/22 + 3/22 + 2 = -1 + 13/22 + 2 = 1 + 13/22 = 1 13/22

2) -1 + 3/5 + 3 = -1 + 3/5 + 3 = -1 + 3 + 3/5 = 2 + 3/5 = 2 3/5

3) -4 + 1/2 * (-1 + 1/3) + 4 = -4 + 1/2 * (-3/3 + 1/3) + 4 = -4 + 1/2 * (-2/3) + 4 = -4 + (-1/3) + 4 = -4 - 1/3 + 4 = -4 + 4 - 1/3 = 0 - 1/3 = -1/3

4) -5 + 1/3 + 4/5 = -5 + 1/3 + 4/5 = -5 + 20/60 + 36/60 = -5 + 56/60 = -5 + 14/15 = -5 14/15

So the final result is: 1 13/22 + 2 3/5 - 1/3 - 5 14/15
