3/6 + 2/6 = 5/6

7/9 + 2/9 = 9/9 = 1

3/5 + 1/5 = 4/5

3/8 + 6/8 = 9/8

2/10 + 5/10 = 7/10

2/7 + 2/7 = 4/7

2 -

3/6 - 2/6 = 1/6

7/9 - 2/9 = 5/9

3/5 - 1/5 = 2/5

6/8 - 3/8 = 3/8

5/10 - 2/10 = 3/10

5/7 - 2/7 = 3/7

3 -

3/6 × 2/6 = 6/36 = 1/6

7/9 × 2/9 = 14/81

3/5 × 1/5 = 3/25

6/8 × 3/8 = 18/64 = 9/32

5/10 × 2/10 = 10/100 = 1/10

5/7 × 2/7 = 10/49

4 -

3/9 : 3/3 = 9/27 = 1/3

2/6 : 4/1 = 8/6 = 4/3

9/5 : 2/1 = 18/5

7/6 : 4/2 = 28/12 = 7/3
