REPEDE va rooooogggg

Answer 1

Răspuns:

• 19,4(5)

Explicație pas cu pas:

5,3(5) = (535 - 53)/90 = 482/90

8,0(9) = (809 - 80)/90 = 729/90

0,(6) = 6/9

0,(1) = 1/9

5,3(5) + 8,0(9)+0,(6) : 0,(1)=

482/90 + 729/90 +  6/9  x  9/1 =

(482+729)/90 +   6/1 =

1211/90 +  6  =

(1211 + 6 x 90) / 90

(1211 + 540) / 90 =

1751/90 =

19,4(5)
