Answer 2

26/39 = 2/3

55/77 = 5/7

39/65 = 3/5

25/35 = 5/7

55/77 = 35/35 

39/65 = 51/85

Answer 3

\(\frac{26}{39}=\frac{2}{3}\)

\(\frac{55}{77}=\frac{5}{7}\)

\(\frac{25}{35}=\frac{5}{7}\)

\(\frac{51}{85}=\frac{3}{5}\)

\(\frac{38}{57}=\frac{2}{3}\)

\(=>\frac{26}{39}=\frac{38}{57},...,...\)
