1、=0.375x96-0.375x1+0.375x5
=0.375x（96-1+5）
=0.375x100
=37.5
2、=2/7÷[(7/8-3/4)x4/5]
=2/7÷[(7/8-6/8)x4/5]
=2/7÷(1/8x4/5)
=2/7x10
=35
3、=6/7-(2/5+3/5)x5/6
=6/7-1x5/6
=36/42-35/42
=1/42
4、=43%x550+45x4.3
=43%x550+450x43%
=43%(550+450)
=43%x1000
=430
=0.375x（96-1+5）
=0.375x100
=37.5
2、=2/7÷[(7/8-3/4)x4/5]
=2/7÷[(7/8-6/8)x4/5]
