Помогите а)5/8:3/4= б)8/9:8/27= в)12/25:3/20= г)5/32:30= д)21/32:35/64=

а) (5/8)/(3/4) = (5/8)*(4/3)=(5/2)*(1/3)=5/6

б) (8/9)/(8/27)=(8/9)*(8/27)=3

в) (12/25)/(3/20)=(12/25)*(20/3)=(4/5)*4=16/5=3(1/5)

г) (5/32)/30 = (5/32)*(1/30)=(1/32)*(1/6)=(1/192)

д) (21/32)/(35/64)=(21/32)*(64/35)=3*(2/5)=6/5=1(1/5)
