Răspuns

Explicație pas cu pas:

2/3+5/6 = 4/6 + 5/6 = 9/6 = 3/2

7/2+1/4 = 14/4 + 1/4 = 15/4

4/5+3/10 = 8/10 + 3/10 = 11/10

5/2+3/5 = 25/10 + 6/10 = 31/10

1/2 - 1/7 = 7/14 - 2/14 = 5/14

6/5-3/7 = 42/35 - 15/35 = 27/35

5/4+7/5 = 25/20 + 28/20 = 53/20

2/3+9/7 = 14/21 + 27/21 = 41/21

1/4+11/3 = 3/12 + 44/12 = 47/12

7/2+1/3 = 21/6 + 2/6 = 23/6

2/5+7/3 = 6/15 + 35/15 = 41/15
