Answer 1

[2,(6)+1/4-1,5]×12/17 =

[(26-2)/9 + 1/4 - 15/10] × 12/17 =

(24/9 + 1/4 - 3/2) × 12/17 =

(8/3 + 1/4 - 3/2) × 12/17 =

( 8×8 + 6 - 3 × 12)/24 × 12/17 =

(64 + 6 - 36)/24 × 12/17 =

(70 - 36)/24 × 12/17 =

34/24 × 12/17 =
(simplificam 24 cu 12, ramane 2 la numitor)
(simplificam 34 cu 17,ramane 2 la numarator)

2/2 =
