Question

9.6×3.7+4.8×2.6简便运算怎么算？

Answer 1

解:
原式
=(4.8x2)x3.7+4.8x2.6
=4.8x(2x3.7)+4.8x2.6
=4.8x7.4+4.8x2.6
=4.8x(7.4+2.6)
=4.8x10
=48

方法:
构造后利用乘法结合律、乘法分配律实现简便计算。

Answer 2

9.6×3.7+4.8×2.6
=9.6×3.7+(4.8×2)×1.3
=9.6×3.7+9.6×1.3
=9.6×(3.7+1.3)
=9.6×5
=48

Answer 3

你好朋友，四点8×2点六可以写成是九点6×1点三这样子两面都有9.6可以把9.6提出，三点7+1点3=5，用九点6×5=48

Answer 4

9.6×3.7+4.8×2.6
=4.8×（2×3.7）+4.8×2.6
=4.8×7.4+4.8×2.6
=4.8×（7.4+2.6）
=4.8×10
=48

Answer 5

9.6×3.7+4.8×2.6
=4.8×2×3.7+4.8×2.6
=4.8×（7.4+2.6）
=4.8×10
=48
