Explicație pas cu pas:
a)
0,2 = 2/10
0,(3) = 3/9 = 1/3
[(1/4 + 2/3)*(-6/11) + 1/10 : 2/10] : 1/3
= [(3/12 + 8/12)*(-6/11) + 1/10*10/2] : 1/3
= [11/12*(-6/11) + 1/2] : 1/3
= (-1/2 + 1/2) : 1/3 = 0
b)
-3/5 = -9/15
-2/3 = -10/15
-9/15 > -10/15
-3/5 > -2/3
c)
x - 2/3 = 7/4
x = 7/4 + 2/3 = 21/12 + 8/12 = 29/12
