Нужно решение, заранее спасибо...

ketlin25 1. 3,452 + 17,23 + 1,548 = (3,452+1,548) + 17,23 = 5 + 17,23 = 22,23

2. 4 * 34,23 * 25 = (4*25) * 34,23 = 100 * 34,23 = 3 423

3. 54 271 + 39 999 + 10 001 = 54 271 + (39 999 + 10 001) = 54 271 + 50 000 =
   = 104 271

4. 56 + 56 + 56 + 56 + 56 + 740 + 740 + 740 = 56*5 + 740*3 = 280 + 2 220 =
   = 2 500
