Explicație pas cu pas:
a)=100*(1/32*8/1+1/4*35/10+3/4)=
=100*(1/4+1/4*35/10+3/4)=
=100*(1/4+35/40+3/4) = ( primul si al doilea nr din paranteza imultesti cu 10)
=100*(10/40+35/40+30/40)=
=100*(75/40)=
=375/2 = 187,5
b)=5/9:[-3/6*(-27)]^-2=
=5/9:(81/6)^-2=
=5/9:[1/(81/6)^2]=
=5/9:36/6561=
=3645/36 = 101,25
