Answer 1

125/25 = 5/1 = 5  (am simplificat prin 25)

13/169 = 1/13 (am simplificat prin 13)

24 si 1/2/(7/10) = (49/2)/(7/10) = 49/2 x 10/7 = 7/1 x 5/1 = 35

0,(2)/0,(4) = (2/9)/(4/9) = 2/9 x 9/4 = 1/1 x 1/2 = 1/2

3,(5)/1,(6) = [(35-3)/9]/[(16-1)/9] = (32/9)/(15/9) = 32/9 x 9/15 = 32/15 = 192/90 = (213-21)/90 = 2,1(3)

2,3(6)/(3/4) = [(236-23)/90] / (3/4) = 213/90 x 4/3 = 71/45 x 2/1 = 142/45 = 284/90 = (315-31)/90 = 3,1(5)
