Вычислите удобным способом.
1) (28 * 16) : 14 = (28 : 14) * 16 =
2) (50 * 210) : 70 =
3) (27 * 25) : 15 =
4) (48 * 64) : 3 : 4 =
(28 * 16) : 14 = (28 : 14) * 16 = 2 * 16 = 32
(50 * 210) : 70 = (210 : 70) * 50 = 3 * 50 = 150
(27 * 25) : 15 = (27 * 25) : (3 * 5) = (27 : 3) * (25 : 5) = 9 * 5 = 45
(48 * 64) : 3 : 4 = (48 * 64) : 12 = (48 : 12) * 64 = 4 * 64 = (40 + 20 + 4) * 4 = 40 * 4 + 20 * 4 + 4 * 4 = 160 + 80 + 16 = 240 + 16 = 256
