Explicație pas cu pas:
|- 0,4| + |0,1| × (- 2/3)
= |- 4/10| + |1/10| × (- 2/3)
= |- 2/5| + 1/10 × (- 2/3)
= 2/5 - 2/30
= 2/5 - 1/15 = 6/15 - 1/15 = 5/15 = 1/3
______________
2/5 - (- 3/2)² : 5/8
= 2/5 - (3/2)² × 8/5
= 2/5 - 9/4 × 8/5
= 2/5 - 72/20 = 2/5 - 18/5 = - 16/5
______________
(- 1/2)² × 16/3 - 5/6 : (- 5/2)
= (1/2)² × 16/3 + 5/6 × 2/5
= 1/4 × 16/3 + 10/30
= 16/12 + 1/3 = 4/3 + 1/3 = 5/3
______________
- 3,5 : (- 14) + 0,25 × 3
= 3,5 : 14 + 0,75
= 0,25 + 0,75 = 1
