Question

2.84×4.6+2.84x5.3+0.284怎么简便计算？

Answer 1

2.84×4.6+2.84x5.3+0.284
=2.84×4.6+2.84x5.3+2.84x0.1
=2.84x（4.6+5.3+0.1）
=2.84x10
=28.4

Answer 2

2.84×4.6+2.84x5.3+0.284
＝2.84×4.6+2.84x5.3+2.84× 0.1
＝2.84×（4.6＋5.3＋0.1）
＝2.84×10
＝28.4

Answer 3

简便计算如下：
2.84×4.6+2.84×5.3+0.284
=2.84×4.6+2.84×5.3+2.84×0.1
=2.84×（4.6+5.3+0.1）
=2.84×10
=28.4

Answer 4

由题，2.84*4.6+2.84*5.3+0.284=2.84*（4.6+5.3）+2.84*0.1=2.84*（4.6+5.3+0.1）=2.84*10=28.4

Answer 5

你好！
根据描述，可以得到：
2.84×4.6＋2.84×5.3＋0.284
＝2.84×（4.6＋5.3）＋0.284
＝2.84×9.9＋0.284
＝2.84×（10－0.1）＋0.284
＝28.4－0.284＋0.284
＝28.4
希望能够帮到你！
