Răspuns:

Explicație pas cu pas:

5/3-2/3 = (5-2)/3 = 3/3 = 1

7/12-5/12= (7-5)/12 = 2/12⁽² = 1/6

17/8-3/8 =(17-3)/8 = 14/8⁽² = 7/4

14/5-3/5= (14-3)/5 = 11/5

⁵⁾3/4-⁴⁾1/5 = (15-4)/20 = 11/20

³⁾7/8-⁴⁾5/6 = (21-20)/24 = 1/24

31/12-⁴⁾4/3 = (31-16)/12 = 15/12⁽³ = 5/4

²⁾1/3-1/6 = (2-1)/6 = 1/6

³⁾15/8-²⁾11/12 =  (45-22)/24 = 23/24

³⁾13/22-²⁾5/33 = (39-10)/66 = 29/66

⁷⁾8/15-³⁾3/35 = (56-9)/105 = 47/105

⁷⁾3/8-⁴⁾5/14 = (21-20)/56 = 1/56
