简便算法:1/8x73/100x25x32、5/11x34x1/10x2/51、8/9x[3/4-(7/16=1/4)]
你好：
1/8×73/100×25×32
=(25×73/100)×(32×1/8)
=73/4×4
=73
5/11×34×1/10×2/51
=(5/11×2/51×1/10)×34
=1/(11×51)×34
=2/(11×3)
=2/33
8/9×[3/4-(7/16-1/4)]
=8/9×[3/4-7/16+1/4]
=8/9×[1-7/16]
=8/9×9/16
=1/2
再问： 谢谢!麻烦在帮忙做下这几道: 9/20x25x5/4x32 1/3x11/33除以5
再答： 9/20×25×5/4×32 =(9/20×25)×(5/4×32) =45/4×40 =450 1/3×11/33÷5 =11/99×1/5 =1/9×1/5 =1/45
1/8×73/100×25×32
=(25×73/100)×(32×1/8)
=73/4×4
=73
5/11×34×1/10×2/51
=(5/11×2/51×1/10)×34
=1/(11×51)×34
=2/(11×3)
=2/33
8/9×[3/4-(7/16-1/4)]
=8/9×[3/4-7/16+1/4]
=8/9×[1-7/16]
=8/9×9/16
=1/2
再问： 谢谢!麻烦在帮忙做下这几道: 9/20x25x5/4x32 1/3x11/33除以5
再答： 9/20×25×5/4×32 =(9/20×25)×(5/4×32) =45/4×40 =450 1/3×11/33÷5 =11/99×1/5 =1/9×1/5 =1/45
