Answer 1

Zapiszę tak ,jak zrozumiałam;
a)
182[(1+1/3+1/27)/(2+2/3+2/27):(4+4/49-4/343)/(1+1/49-1/343)]x(80808080)/(91919191)=
182[(1+9/27+1/27)/(2+18/27+2/27):(4+28/343)/(1+7/343-1/343)]x(80808080)/(91919191)=
182[(37/27)/(74/27):(1396/343)/(349/343)]x(80808080)/(91919191)=
182[(37/27)x(27/74):(1396/343)x(343/349)]x(80808080)/(91919191)=
182[37/74:1/4]x(80808080)/(91919191)=
182[37/74x4/1]x(80808080)/(91919191)=
182[2]x(80808080)/(91919191)=
364x(80808080)/(91919191)=
4x(80808080)/(1010101)=
=80

b)
985x654654
