Answer 1

Answer:

Step-by-step explanation:

1) -1/2 + 1/3

= -1x3/2x3 + 1x2/2x3

= -3/6 + 2/6

= -3 + 2/6

= -1/6

2) 3/4 + 1/2

= 3x2/4x2 + 1x4/2x4

= 6/8 + 4/8

= 10/8 = 5/4

3) 1/5 + 2/3

= 1x3/5x3 + 5x2/3x5

= 3/15 + 10/15

= 3 + 10/15

= 13/15

4) -9/16 + 9/16

= -9 +9/16

= 0/16

5) 1/4 + -2/3

= 1x3/4x3 - 2x4/3x4

= 3/12 - 8/12

= 3-8/12

= -5/12

6) 8/15 - 15/8

= 8x8/15x8 - 15x15/8x15

= 64/120 - 225/120

= 64 - 225/120

= -161/120
