(1) (-3)×(-5/6)×(-9/5)×(-4)
=3*5/6*9/5*4
=18
(2) 丨-1 1/6丨×(-1 1/2)×(-1 1/3)×丨-1 2/7丨 (这里分别是1又几分之几)
=7/6*3/2*4/3*9/7

(3)(-32)×(-0.25)×(-1.25)
=-(4*0.25)*(8*1.25)
=-10
(4)(1/4-1/12-1/36)÷(-1/5)×36
=(1/4-1/12-1/36)×36÷(-1/5)
=-(1/4*36-1/12*36-1/36*36)*5
=-25
(5)-19 24/25×(-5)
=(-19+24/25)*(-5)
=19*5-24/25*5
=90又1/5
(6)(-8)×(-8 3/7)+(-7)×(-8 3/7)-8 3/7×15
=(-8 3/7)*(-8-7+15)
=0
