Answer 1

Resposta:

1/5

1/5 + 1/2 = 7/10

1/5 + 3/4 = 19/20

4

4/1 + 1/2 = 9/2

4/1 + 3/4 = 19/4

4/1 + 2/3 = 14/3

7/3

7/3 + 1/2 = 17/6

7/3 + 3/4 = 37/12

7/3 + 2/3 = 9/3

-----------------------------------------

9/10

9/10 - 2/5 = 25/50

9/10 - 1/4 = 26/40

9/10 - 3/8 = 51/80

1

1/1 - 2/5 = 3/5

1/1 - 1/4 = 3/4

1/1 - 3/8 = 5/8

5/4

5/4 - 1/4 = 4/4

5/4 - 3/8 = 28 /32
