Question

0.88×0.78+0.11×1.76的简算怎么算？

Answer 1

首先对数的倍数关系要观察记忆特点，这个题目中1.76＝0.88×2，所以整个式子变成0.88×0.78+0.11×0.78×2，然后注意两边都有0.78，用乘法分配律得0.78×（0.78＋0.11×2）＝0.78×1＝0.78。如果回答对你有帮助的话，希望采纳谢谢。有什么不懂再问，可以的话再加一个关注。

Answer 2

0.88=0.11*8

0.78*2=1.56
所以原式可以化为(0.11*0.78*8)+0.11*(1.56+0.2)
=0.11*(1.56*4)+0.11*1.56+0.11*0.2
=0.11*(1.56*5)+0.11*0.2
=0.11*7.8+0.11*0.2
=0.11*8
=0.88

Answer 3

0.88×0.78+0.11×1.76
=0.88*0.78+0.11*8*0.22
=0.88*（0.78+0.22）
=0.88

0.88×0.78+0.11×1.76
=0.11*8*0.78+0.11*1.76
=0.11*（6.24+1.76）
=0.11*8
=0.88

Answer 4

0.88×0.78+0.11×1.76
=0.88×0.78+0.11×8×0.22
=0.88×(0.78+0.22)
= 0.88

Answer 5

0.88×0.78+0.11×1.76
＝0.88×0.78+0.11×2×0.88
＝0.88×(0.78+0.11×2)
＝0.88
请采纳，谢谢。
