抱歉,我没买

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

高伯伯比周叔叔=4比6
高伯伯:5/(4+6)*4=2万元
周叔叔:5/(4=6)*6=3万元

从12时到24时时针走过一圈。分针走过12圈
时针走过面积=π*4*4
分针走过面积=π*5*5*12
=300π
16π/300π*100%=5.3%
时针扫过的面积是分针扫过面积的5.3%
