Explicație pas cu pas:
a = 5/9*9/25 - 2/25*25/10 = 1/5 - 1/5 = 0
________
0,8(3) = (83 - 8)/90 = 75/90 = 5/6
b = 3/2*(29/9 - 10/3)^2 + 5/6 = 3/2*(29/9 - 30/9)^2 + 5/6 = 3/2*1/81 + 5/6
= 1/54 + 5/6 = 1/54 + 45/54 = 46/54 = 23/27 = 0,(851)
_________
c = 0,2 - 0,2*(3/4 - 1/4) = 0,2 - 2/10*2/4 = 2/10 - 1/10 = 1/10 = 0,1
_________
a < c < b
