Answer 2

А)1) 7470/18=415
2) 415-319=96
3) 103*20=2060
4) 24*45=1080
5)2060-1080=980
6)980/28=35
7)415+35=450

Answer 3

а) (7470:18-319) + (103*20-24*45):28 = (415 - 319) + (2060 - 1080):28 = 96 + 980:28 = 96 + 35 = 131

б) 21*55 + (107209-21696) - (78+8664:76) = 1155 + 85513 - (78+114) = 1155 + 85513 - 192 = 86668 - 192 = 86476
