1) 6, 2/3 + 2, 4/15 = 20/3 + 34/15 = 134/15

2)134/15 + 5, 1/2 = 134/15 + 11/2 = 433/30

3)30 : 5/28 = 30 * 28/5 = 168

4)433/30 : 1/15 = 433/2

5)433/2 - 168 = 97/2

 

6)5 * 4/5 = 4

7)3/5 * 5/22 = 3/22

8)4 - 3/22 = 3, 22/22 - 3/22 = 3, 19/22

9)3, 19/22 * 48, 1/2 = 85/22 * 97/2 = 8245/44

 

10)97/2 : 8245/44 = 22/85
