7.2x1.25 =0.9x(8x1.25) =0.9x10 =9 朋友,请及时采纳正确答案,下次还可能帮到您哦,您采纳正确答案,您也可以得到财富值,谢谢。

64X0.25X0.5X1.25 =(4x2x8)x0.25x0.5x1.25 =(4x0.25)x(2x0.5)(8x1.25) =1x1x10 =10 运用乘法交换律、结合律。 希望能帮到你!

1.25x0.25x3.2 =(1.25x8)x(0.25x0.4) =10x0.1 =1

1.25x0.25x0.05x64 =1.25x0.25x0.05x8×8 =1.25x8x0.25x(0.05x8) =10x0.25x0.4 =2.5x0.4 =1

=0.25×4×8×1.25 =(0.25×4)×(8×1.25) =1×10 =10

解:采用凑整法, 原式=1.25x3.5x0.25 =1.25x8x(3.5x2)x(0.25x4)÷(2x4x8) =10x7x1÷64 =70/64 =35/32

1.25x(4x8)x2.5 1.25x8x(2.5x4) =10x10 100

1.25x0.32x2.5 +2.5简便计算 1.25x0.32x2.5 +2.5 =2.5*(1.25*0.32+1) =2.5*1.4 =3.5

1.25x3.2x0.25= 1.25*0.88*4*0.25= 1*1=1 采纳吧

1.25÷0.25 =(1.25×4)÷(0.25×4) =5÷1 =5
