Answer 1

1) 5/8-(-5/8)= 5/8 + 5/8 = 10/8 = 1 i 2/8 = 1 i 1/4

2) -5/8-(-5/8)= -5/8 + 5/8 = 0

3) 1/3-1= 1/3 - 3/3 = - 2/3

4) -1/3-1= - 1 i 1/3

5) -2 1/5 - ( - 2/5)= - 2  1/5 + 2/5 = - 1  6/5 + 2/5 = - 1  4/5

6) -3 5/7 - ( - 1 6/7)= -3  5/7 + 1  6/7 = - 2  12/7 + 1  6/7 = - 1  6/7
7) 6-11 3/8 = - 5  3/8
8) - 7/5 - ( - 7/6)= - 7/5 + 7/6 = - 42/60 + 35/30 = -7/30
9) -(-3/4)-1/2 = 3/4 - 1/2 = 3/4 - 2/4 = 1/4
10) -(-7/8) - ( - 3/4)= 7/8 + 3/4 = 7/8 + 6/8 = 13/8 = 1  5/8
11) - 1/6 - 5/12= - 2/12 - 5/12 = - 7/12
12) - 3/5 - (-4/7) = - 3/5 + 4/7 = - 21/35 + 20/35 = - 1/35
13) - 2 3/10 - 1 2/15= - 2  9/30 - 1  4/30 = - 3  13/30
14) 9/10- 5 7/8 = 36/40 - 5  35/40 = 36/40 - 4  75/40 = - 4  39/40
15) 2 2/5 - 3 1/3 = 2  6/15 - 3  5/15 = 2  6/15 - 2  20/15 = - 14/15

Answer 2

15)

 

2 2/5 - 3 1/3= 12/5 - 10/3= 36/15 - 50/15 = - 14/15
