Question

6.8×3.65+3.19×3.65简便计算

Answer 1

6.82×3.65+3.19×3.65
=3.65×（6.82+3.19）
=3.65×10
=36.5
本题运用乘法分配：a×（b+c）=a×b+a×c
看一下你的题目是否正确哦。
=3.65×（6.8+3.19）
=3.65×9.99
=3.65×（10-0.01）
=3.65×10-3.65×0.01
=36.5-0.0365
=36.4635

Answer 2

6.8×3.65+3.19×3.65
=3.65×(6.8+3.19)
=3.65×9.99
=3.65×(10-0.01)
=3.65×10-3.65×0.01
=36.5-0.0365
=36.4635

Answer 3

6.8×3.65+3.19×3.65
=3.65*（6.8+3.2-0.01）
=3.65*（6.8+3.2）-0.0365
=3.65*10-0.0365
=36.5-0.0365
=36.4635

Answer 4

6.8×3.65+3.19×3.65
=3.65×(6.8+3.19)
=3.65×(6.8+3.2-0.01)
=3.65×(10-0.01)
=36.5-0.0365
=36.4635

Answer 5

你好，这道题简便计算是利用乘法分配律计算。原式=(6.8+3.19)x3.65=9.99x3.65=(10-0.01)x3.65=10x3.65-0.01x3.65=36.5-0.0365=36.4635。
