Answer 1

1) 1/3 + 4/6

1/3 + 2/3

1 + 2/3

3/3

= 1

2) 3/2 + 2/3

3.3/2.3 + 2.2/3.2

9/6 + 4/6

9 + 4/6

= 13/6

3) 3/4 + 5/6

3.3/4.3 + 5.2/6.3

9+10/12

= 19/12

4) 1/2 + 1/3 + 1/5

1.15/2.15 + 1.10/3.10 + 1.6/5.6

15/30 + 10/30 + 6/30

= 31/30

5) 3/2 – 2/3

3.3/2.3 - 2.2/3.2

9/6 - 4/6

9-4/6

= 5/6

6) 5/6 – 3/4

5.2/6.2 - 3.3/4.3

10/12 - 9/12

= 1/12

7) 1/2 – 1/3 – 1/6

1.3/2.3 - 1.2/3.2 - 1/6

3/6 - 2/6 - 1/6

3 - 2 - 1/6

= 0

8) 4/6 – 1/3

2/3 - 1/3

2-1/3

= 1/3
