va rog ex 2. am nevoie urgent​

Answer 1

Răspuns:

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
