答案和解析
1.（1-3/4-7/8)x(-1/5)
=（1-6/8-7/8)x(-1/5)
=（-5/8)x(-1/5)
=1/8
2.（-3又1/3)x(-0.12)x(2又1/4)x33又1/3)
=（-10/3)x(-12/100)x(9/4)x100/3
=36
3.（-0.1)x(-1)x(-100)-0.01x(1000)
=-10-10
=-20
4.-100x1/8-0.125x35.5+14.5x(-12.5%)
=-100x1/8-1/8x35.5-14.5x1/8
=-(100+35.5+14.5)x1/8
=-150/8
=-75/4
5.0.125除8/3
=8/3 / (1/8)
=8/3 *8
=64/3
6.-5/6x(12-2又2/5-0.6)
=-5/6x(12-2.4-0.6)
=-5/6x(12-3)
=-5/6x9
=-15/2
=（1-6/8-7/8)x(-1/5)
=（-5/8)x(-1/5)
=1/8
2.（-3又1/3)x(-0.12)x(2又1/4)x33又1/3)
=（-10/3)x(-12/100)x(9/4)x100/3
=36
3.（-0.1)x(-1)x(-100)-0.01x(1000)
=-10-10
=-20
4.-100x1/8-0.125x35.5+14.5x(-12.5%)
=-100x1/8-1/8x35.5-14.5x1/8
=-(100+35.5+14.5)x1/8
=-150/8
=-75/4
5.0.125除8/3
=8/3 / (1/8)
=8/3 *8
=64/3
6.-5/6x(12-2又2/5-0.6)
=-5/6x(12-2.4-0.6)
=-5/6x(12-3)
=-5/6x9
=-15/2
