Question

2.67×9.8+0.2用简便运算的过程？

Answer 1

2.67×9.8+0.2
＝（2.67×10-2.67×0.2）+0.2
＝（26.7-0.534）+0.2
＝26.166+0.2
＝26.366

Answer 2

2.67*（10-0.2）+0.2=2.67*10-2.67*0.2+0.2=26.7-（2.67-1）*0.2=26.7-1.67*0.2=26.7-0.334=26.366

Answer 3

2.67×9.8+0.2简便运算的过程
=2.67x(10-0.2)+0.2
=2.67x10-2.67x0.2+0.2
=26.7-0.2x(2.67-1)
=26.7-0.2x1.67
=26.7-0.334
=26.366

Answer 4

2.67×9.8+0.2
=2.67×（10—0.2）+0.2
=2.67×10—2.67×0.2+0.2
=26.7—（2.67×0.2—0.2）
=26.7—（（2.67—1）×0.2）
=26.7—1.67×0.2
=26.7—0.334
=26.366

Answer 5

把9.8看作是10-0.2，所以
原式=2.67×10+0.2-2.67×0.2
=26.7+0.2-0.534
=26.900-0.534=26.366，希望采纳，谢谢。
