Question

Como se soma as dízimas:
1,444... + 0,1555...
2,333... + 0,2666...

Answer 1

1,4444... = 1 + 4/9 = 13/9
0,15555  = (15 - 1)/90 = 14/90
2,3333.. = 2 + 3/9  =  21/9
0,26666... = (26-2)/90 = 24/90
13/9 + 21/9 + 14/90 + 24/90
34/9 + 38/90=  340/90 + 38/90 = 378/90 = 126/30= 42/10 = 21/5 = 4,2
