Question

0.65×7.6+0.24×6.5简便方法？

Answer 1

0.65×7.6+0.24×6.5的简便方法是：
0.65×7.6+2.4×0.65
=0.65×（7.6+2.4）
=0.65×10
=6.5

Answer 2

0.24×6.5=1.56，那么可以换算成0.65×2.4=1.56，算式你可以换成0.65×7.6+2.4×0.65=0.65×（7.6+2.4）=6.5。这个最简便。要不然就得硬算。

Answer 3

0.65×7.6+0.24×6.5
=6.5×0.76+0.24×6.5
=6.5*（0.76+0.24）
=6.5*1
=6.5

Answer 4

0.65×7.6+0.24×6.5

把 0.65×7.6 变成 6.5×0.76

=6.5×0.76+0.24×6.5

利用 axb+axc = ax(b+c)

=6.5×(0.76+0.24)

计算 0.76+0.24=1

=6.5x1

=6.5

Answer 5

0.65乘以7.6等于6.5乘以0.76.0.76+0.24等于1.1乘以6.5等于6.5
