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
1/8×73/100×25×32
=(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
