a) 1/5 = 5

b) 1/4 + 1/6 + 1/12 = 3/12 + 2/12 + 1/12 = ( 3+2+1)/12 = 6/12 = 1/2

c) 20/35 : (4/7) = 20/35 * 7/4 = 5/5 = 1

d) ( 3/2 + 4/3 + 5/4 )² * ( 2/4 - 1/4 - 1/6 - 1/12 ) = ( 49/12 )² × 0 = 0
a) 5
b) 1/4+1/6+1/12=(3+2+1)/12=6/12=1/2
c) (20/35):(4/7)=(20/35)*(7/4)=20*7/35*4=140/140=1
d) [tex] (3/2+4/3+5/4)^{2} [/tex]*(2/4-1/4-1/6-1/12)=
[tex] [(18+16+15)/12^{2} [/tex]*[(6-3-2-1)/12=
[tex] 49/12^{2} [/tex]*0=0
