Answer 1

解答如图片所示

Answer 2

(1)
7.6×0.8+0.2×7.6
=7.6×(0.8+0.2)
=7.6×1
=7.6(运用乘法分配律)
(2)
0.85×9.9
=0.85×(10-0.1)
=0.85×10-0.85×0.1
=8.5-0.085
=8.415(运用乘法分配律)
(3)
0.25×8.5×4
=0.25×4×5
=1×5
=5(运用乘法结合律)
(4)
1.28×8.6+0.72×8.6
=8.6×(1.28+0.72)
=8.6×2
=17.2(运用乘法分配律)
(5)
12.5×0.96×0.8
=12.5×0.8×0.96
=10×0.96
=9.6(运用乘法结合律)
(6)
10.6×0.35-9.6×0.35
=0.35×(10.6-9.6)
=0.35×1
=0.35(运用乘法分配律)

Answer 3

那就等于12.5×0点8×0点96。
等于10×0.96
等于9.6

Answer 4

我写给你计算过程:
12.5×0.96×0.8
=（12.5×0.8）×0.96
=10×0.96
=9.6
所以，这个题最后的结果就是9.6。

Answer 5

12.5x0.96x0.8
=12.5x0.8x0.96
=10x0.96
