b)

25/275  si 6/44

25⁽²⁵/175⁽²⁵= 1/7 ............................................................se simplifica prin 25

6⁽²/44⁽²=    3/22 ...............................................................se simplifica prin 2

²²⁾1/7 si ³⁾3/22 ............................................................se amplifica cu 22 si 3

22/154 si 9/154 ..................................................154 acelasi numitor comun
