Question

(1 /2+3/4+5/6)+(1/2+1/4+1/6)=​

Answer 1

Răspuns:

mai intai trb. sa amplificam fiecare fractie, astfel incat sa avem acelasi numitor.

Deci amplificam pana cand ne da 12

(6/12 + 9/12 + 10/12) + (6/12 + 3/12 + 2/12)

25/12 + 11/12= 36/12( acum simplificam cu 12)

= 3

Answer 2

(1/2+3/4+5/6) + (1/2+1/4+1/6) =

= 1/2+1/2 + 3/4+1/4 + 5/6+1/6

= (1+1)/2 + (3+1)/4 + (5+1)/6

= 2/2 + 4/4 + 6/6

= 1 + 1 + 1

= 3
