0.25×3/12×3/26×4/9脱式计算？

Answer 1

脱式计算如下所示
0.25×3/12×3/26×4/9
=1/4×3/12×3/26×4/9
=1/4×4/9×3/12×3/26
=1/9×3/12×3/26
=1/36×3/26
=1/312

Answer 2

0.25*12/13*26/3*9/4 =12/13*26/13*1/4*9/4 =9/2 直接就是交叉想乘，注意约分要约尽，再最后计算的时候不要有遗漏就行

Answer 3

0.25×3/12×3/26×4/9
=(0.25×3×3×4)/(1x12×26×9)
=(0.25×4×1×1)/(1x4×26×3)
=1/312

Answer 4

0.25X3/12X3/26X4/9
=1/4X1/4X3/26X4/9
=1/4X1/78
=1/312

Answer 5

化简

=0.25/108
=1/432
