Răspuns:

Explicație pas cu pas:

0,1(6) = (16 - 1)/90 = 15/90 = 1/6

1 3/4 = 7/4

0,25 = 25/100 = 1/4

0,(3) = 3/9 = 1/3

2 3/4 = 11/4

__________

1/6 - [(1/4 - 7/4) - (1/3 - 11/4)]

= 1/6 - [-6/4 - (4/12 - 33/12)]

= 1/6 - (-6/4 + 29/12)

= 1/6 - (-18/12 + 29/12)

= 1/6 - 11/12

= 2/12 - 11/12

= -9/12 = -3/4
