a)0,12*3/4-(3/5-2,1*5/7)=0,09-(3/5-21/10*5/7)=0,09-(3/5-1,5)=0,09-(-0,09)=0,09+0,09=0,18
b)((32/10+7/8):25/10-62/10)*(-100/3)=((163/40*10/25-62/10)*(-100/3)=(1,63-6,2)*
(-100/3)=-4,57*(-100/3)=457/3=152i1/3
c)4*(0,6-3/5:(-3))=4*((0,6-(-0,2))=4*0,8=3,2
d)((7/3-7/4)+5/12):0,10=((28/12-21/12)+5/12):0,10=(7/12+5/12):0,10=12/12:0,10=
1:0,10=10
e)(-1/9+7/6):(1/6-4/3)=(-6/54+63/54):(1/6-8/6)=57/54:(-7/6)=57/54*(-6/7)=-0,90
