Answer 1

Răspuns:

Explicație pas cu pas:

c) 1/2: 0,5 = 0,5:0,5 = 1

0,(3) +1/3:2 = 1/3 +1/6 = 3/6 =1/2

1:(0,2 +4*1/2) + 1/11 = 1:(22/10) +1/11 =

10/22 +1/11 = 5/11+1/11 = 6/11

d) 2,(6) = (26-2)/9 = 24/9 = 8/3

0,(4) = 4/9

(2 +8/3:4/9 - 12/10:3/10)*1/4 =

(2 +8/3*9/4 - 12/10*10/3)*1/4 =

(2 + 6 - 4)*1/4 = 4/4 = 1
