Вычисли удобным (1000 + 200 + 50) / 5 (8000 + 1200 1800)/5 (10000 + 300 + 300) / 2 (10400 + 12600 + 1000) /4 (5600+1300+30000) / 6 (20000+5000+500 + 10) / 5

1) (1000 + 200 +50): 5 = 200 + 40 + 10 = 250

2) (8 000 + 1 200 + 1 800): 5 = 1600 + 240 + 360 = 2200

3) (10 000 + 300 + 300): 2 = 5000 + 150 + 150 = 5300

4) (10 400 + 12 600 +1 000): 4 = 2600 + 3150 + 250 = 6000

5) (5 600 +1 300 + 30 000): 6 = 36900 / 6 = 6150

6) (20 000 + 5 000 +500 + 10): 5 = 4000 + 1000 + 100 = 5100
