Question

2,569-(1-0,15)+0,286+(13,09-0,574)

Answer 1

2,569-(1-0,15)+0,286+(13,09-0,574)=2,569-1+0,15+0,286+13,09-0,574=14,521
ОТВЕТ: 14,521

Answer 2

2,569 - (1 - 0,15) + 0,286 + (13,09 - 0,574) = 14,521

 1) 1 - 0,15 = 0,85
  2) 13,09 - 0,574 = 12,516
   3) 2,569 - 0,85 = 1,719
    4) 1,719 + 0,286 = 2,005
     5) 2,005 + 12,516 = 14,521
