小数简便计算，谢谢！

Question

如题所述

Answer 1

(0.75×2.6×2.7)÷(0.13×0.25×9)
=(0.75÷0.25)×(2.6÷0.13)×( 2.7÷9)
=3×20×0.3
=18

解答分析：
运用结合律，把被除数的因数分别与除数的因数相除，
再把所得的商相乘，可以使计算简便。

Answer 2

(0.75/0.25)x(2.6/0.13)x(2.7/9)
=3x20x0.3
=18
请采纳！！！

Answer 3

(0.75*2.6*2.7)/(0.13*0.25*9)
=(0.75/0.25)(2.6/0.13)( 2.7/9)
=3*20*0.3=18

Answer 4

Answer 5

0.75X2.6X2.7÷0.13÷0.25÷9
交换律：0.75÷0.25X2.6÷0.13X2.7÷9
= 3X20X0.3

=18
