Answer 1

1:

2/4 + 5/1 - 2/10

 2/4 x 5 = 10/20

 1/5 x 4 = 4/20

2/10 x 2 = 4/20

10/20 + 4/20 -  4/20 = 10/20

2:

 3/4 + 3/2 + 2/8

 1/4 x 2 = 6/8

 3/2 x 4 = 12/8

2/8 x 1 = 2/8

6/8 + 12/8 - 2/8 = 16/8

3:

15/10 - 2/2 + 2/5

 15/10 x 1 = 15/10

 2/2 x 5 = 5/10

2/5 x 2 = 4/10

15/10 - 10/10 + 4/10 = 9/10
