Пошаговое объяснение:
1) 12,918 - (4,918 + 3,4) = 12,918 - 4,918 - 3,4 = 8 - 3,4 = 4,6
3) (13,245 + 9,88) – 6,88 = 13,245 + 9,88 – 6,88 = 13,245 +3 = 16,245
2) (6,403 + 8,715) – 2,403 = 6,403 + 8,715 – 2,403 =
= 6,403– 2,403 + 8,715 = 4 + 8,715 = 12,715
4) 11,703 - (5,4 + 2,703) = 11,703 - 5,4 - 2,703=
= 11,703 - 2,703 - 5,4 = 9 - 5,4 = 3,6
