Answer 1

Răspuns:

= 0

Explicație pas cu pas:

(2/3+5,13÷9)÷3 71/100-0(3)​ = ?

5,13 = 513/100

5,13:9 = 513/100 :9 = 513/100 ·1/9 = 513/900⁽⁹ = 57/100 = 0,57

3 71/100 = (3·100+71)/100 = 371/100 = 3,71

0,(3) = 3/9⁽³ = 1/3

---------

(2/3+5,13÷9)÷3 71/100-0(3)​ =

= (¹⁰⁰⁾2/3 + ³⁾57/100) : 371/100 - 1/3 =

= (200+171)/300 · 100/371 - 1/3 =

= 371/300 · 100/371 - 1/3 =

= 1/3 - 1/3 = 0
