Answer 1

Answer:

1. <-----17--------------------------34----------> = 34-17= 17

2. <--3/14-------4/7--------------------------------------> 4/7+3/14= 11/14

3. <-----------14----------------25--------------------> 14+25= 39

4. <-----------------------8.2--------9.3----------------> 8.2-9.3= -1.1

5. <-----------4---------------------------12.5---------> 12.5+4= 16.5

6. <-----------5/8-------------7/10-----------------------> 7/10+ 5/8= 53/40= 1 13/40

Answer 2

1. <-----17--------------------------34----------> = 34-17= 17

2. <--3/14-------4/7--------------------------------------> 4/7+3/14= 11/14

3. <-----------14----------------25--------------------> 14+25= 39

4. <-----------------------8.2--------9.3----------------> 8.2-9.3= -1.1

5. <-----------4---------------------------12.5---------> 12.5+4= 16.5

6. <-----------5/8-------------7/10-----------------------> 7/10+ 5/8= 53/40= 1 13/40
