Answer 1

Răspuns:

Explicație pas cu pas:

3,(6) = (36 - 3)/9 = 33/9 = 11/3

2,25 = 225/100 = 9/4

9/4 : 11/3 = 9/4*3/11 = 27/44

2 3/4 = 11/4

calculul in paranteza patrata

2 - 11/4*27/44 = 2 - 27/16 = 32/16 - 27/16 = 5/16

__________

1,0(6) = (106 - 10)/90 = 96/90 = 32/30 = 16/15

1 : 16/15 = 1*15/16 = 15/16

___________

a = 5/16 : 15/16 = 5/16*16/15 = 5/15 = 1/3

__________

1/a = 3, numar natural
