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

1/8x73/100x25x32
=1/8×73/25*4×25×4×8
=73
5/11x34x1/10x2/51
=5*17*2*2/11*10*17*3
=2/33
8/9x[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

1/8x73/100x25x32=(1/8x32)x(73/100x25)=4x(73/4)=73
5/11x34x1/10x2/51=(5/11x1/10)x2/51x34=1/11x(1/2x2/51)x34=1/11x1/51x34=34/161
8/9x[3/4-(7/16+1/4)]=8/9x3/4-8/9x(7/16+1/4)=2/3-8/9x7/16-8/9x1/4=2/3-7/18-2/9=1/18
