Answer 1

а) $frac{12}{13} +frac{4}{16} +frac{1}{13}+ frac{3}{13}=(frac{12}{13} +frac{1}{13} )+(frac{4}{16} +frac{3}{16} )=1+frac{7}{16} =1frac{7}{16}$

б) $(frac{13}{50} +frac{8}{27} )+(frac{6}{27} +frac{37}{50} )=(frac{13}{50} +frac{37}{50})+(frac{8}{27}  +frac{6}{27} )=1+frac{14}{27} =1frac{14}{27}$

в) $(frac{28}{33} +frac{2}{3} )-frac{28}{33} =(frac{28}{33}-frac{28}{33} )+frac{2}{3} =0+frac{2}{3} =frac{2}{3}$

г) $(frac{6}{7} +frac{18}{19})-frac{18}{19} =frac{6}{7} +(frac{18}{19} -frac{18}{19} )=frac{6}{7}+0=frac{6}{7}$

д) $frac{25}{57} -(frac{2}{57}+ frac{23}{57} )=frac{25}{57} -frac{25}{57}=0$

е) $2-(1frac{1}{3} +frac{2}{3} )=2-2=0$
